FIELD [0002] The present application relates to the fields of chemistry, biochemistry, molecular biology and medicine. The present disclosure related to compounds that can be useful as inhibitors of PD-1, PD-Ll or the PD-1/PD-Ll interaction. Also disclosed herein are pharmaceutical compositions of compounds described herein and uses of or methods of using the compounds for the treatment of PD-L1 related diseases including but not limited to liver diseases, cancer, hepatocellular carcinoma, viral diseases, or hepatitis B. BACKGROUND [0003] The programmed cell death 1 (PD-1) immune checkpoint expressed on the surface of activated CD4 + and CD8 + T cells controls an inhibitory mechanism to prevent autoimmunity. Engagement of PD-1 by programmed death-ligand 1 (PD-L1) expressed on the multitude of cell types, including macrophages, dendritic cells, mast cells as well as cancer cells induces T cell exhaustion resulting in reduction or loss of effector cytokine production (e.g. IL-2, TNF-α, IFN-γ) and upregulation of other inhibitory receptors and immune checkpoints (e.g. CTLA-4, LAG-3, and BTLA), or T cell apoptosis. High expression of PD-L1 is exhibited by many types of cancers to escape tumor immune surveillance and has been associated with poorer prognosis. PD-1-mediated immunosuppression is also linked to some viral infections, such as hepatitis B. There is an ongoing need for PD-1/PD-L1 therapies and improvements thereof for the treatment of disease.

BRIEF DESCRIPTION OF THE DRAWINGS [0009] Figures 1A and 1B show the absolute configuration structure and ORTEP crystal structure of the formate salt of Intermediate 5-1b. DETAILED DESCRIPTION [0010] Hepatocellular carcinoma (HCC) is the most common form of liver cancer. HCC can be caused by a variety of conditions, such as alcohol consumption, cirrhosis, and viral infections that cause hepatitis, such as hepatitis B virus, hepatitis C virus, and hepatitis D virus. The inflammation, fibrosis, and cirrhosis linked with these conditions can induce malignancies in affected liver cells. HCC has relatively poor prognosis, with a five-year survival rate of about 30%, depending on if full surgical resection of the tumor is possible. [0011] For early disease, surgical resection is used. However, most HCC are identified at later stages because of difficulties in diagnosing. Upon late stage diagnosis, the tumors are unresectable and most patients are given systemic therapies. The current standard of care in front line are multi-kinase inhibitors (including, for example, sorafenib and/or lenvatinib). Most patients are refractory or relapse from these treatments, and undergo second line therapies that have anti-angiogenic agents (including, for example, Regorafinib, Cabozantinib, and/or Ramicirumab) or immune checkpoint inhibitors (including, for example, nivolumab and/or pembrolizumab). However, most patients do not respond to first and second therapies, and the clinical benefit is poor, with overall survival not exceeding one year. In addition, biomarker driven therapies are lacking. Thus, there is a need to develop more tolerable and efficacious therapies for the treatment of HCC and related liver disorders. [0012] HBV is a partially double-stranded circular DNA of about 3.2 kilobase (kb) pairs, and is classified into eight genotypes, A to H. The HBV replication pathway has been studied in great detail. One part of replication includes the formation of the covalently closed circular DNA (cccDNA) form. The presence of the cccDNA gives rise to the risk of viral reemergence throughout the life of the host organism. HBV carriers can transmit the disease for many years. An estimated 300 million people are living with hepatitis B virus infection, and it is estimated that over 750,000 people worldwide die of hepatitis B each year. In addition, immunosuppressed individuals or individuals undergoing chemotherapy are especially at risk for reactivation of an HBV infection. HBV can be acute and/or chronic. Acute HBV infection can be either asymptomatic or present with symptomatic acute hepatitis. [0013] HBV can be transmitted by blood, semen, and/or another body fluid. This can occur through direct blood-to-blood contact, unprotected sex, sharing of needles, and from an infected mother to her baby during the delivery process. The HBV surface antigen (HBsAg) is most frequently used to screen for the presence of this infection. Currently available medications do not cure HBV and/or HDV infection. Rather, the medications suppress replication of the virus. [0014] The hepatitis D virus (HDV) is a DNA virus, also in the Hepadnaviridae family of viruses. HDV can propagate only in the presence of HBV. The routes of transmission of HDV are similar to those for HBV. Transmission of HDV can occur either via simultaneous infection with HBV (coinfection) or in addition to chronic hepatitis B or hepatitis B carrier state (superinfection). Both superinfection and coinfection with HDV results in more severe complications compared to infection with HBV alone. These complications include a greater likelihood of experiencing liver failure in acute infections and a rapid progression to liver cirrhosis, with an increased risk of developing liver cancer in chronic infections. In combination with hepatitis B, hepatitis D has the highest fatality rate of all the hepatitis infections, at 20%. There is currently no cure or vaccine for hepatitis D. [0015] Programmed cell death 1, or programmed death 1 (PD-1) is a 268 amino acid long type I transmembrane protein found as a surface marker on T cells and other immune cells. As an immune checkpoint, PD-1 serves to negatively regulate immune responses to prevent autoimmune disorder. PD-1 protein (NCBI accession number NP_005009.2) is expressed from the cluster of differentiation 279 (CD279) gene (NCBI accession number NG_012110.1) or mRNA transcript (NCBI accession number NM_005018.3). In some preferred embodiments, PD-1 is the human PD-1 protein, and CD279 is the human CD279 transcript or gene on chromosome 2. It should be understood that a person with ordinary skill in the art would view the terms PD-1 and CD279 as often nominally interchangeable when considering the nucleic acid (DNA or RNA) or corresponding translated protein, or the sequences thereof. [0016] Programmed cell death-ligand 1, or programmed death-ligand 1 (PD-L1), also known as B7 homolog 1 (B7-H1) is 272 amino acid long type I transmembrane protein found as a surface marker on many different cell types. PD-L1 is a major ligand of PD-1 and results in inhibition of T cell cytotoxicity and cytokine production. Cancer cells such as HCC cells take advantage of this immune checkpoint by upregulating PD-L1 expression, resulting in dysfunctional anti-tumor immunity by proximal T cells. Viruses also have been observed to modulate the PD-1/PD-L1 pathway to inhibit immune host response. Hepatitis B virus has been shown to upregulate PD-L1 in infected hepatocytes, and PD-1 in associated T cells. PD- L1 protein (NCBI accession number NP_054862.1) is expressed from the cluster of differentiation 274 (CD274) transcript (NCBI accession number NM_014143.4). In some preferred embodiments, PD-L1 is the human PD-L1 protein, and CD274 is the human CD274 transcript or gene on chromosome 9. It should be understood that a person with ordinary skill in the art would view the terms PD-L1 and CD274 as often nominally interchangeable when considering the nucleic acid (DNA or RNA) or corresponding translated protein, or the sequences thereof. Definitions [0017] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. All patents, applications, published applications and other publications referenced herein are incorporated by reference in their entirety unless stated otherwise. To the extent publications and patents or patent applications incorporated by reference contradict the disclosure contained in the specification, the specification is intended to supersede and/or take precedence over any such contradictory material. In the event that there are a plurality of definitions for a term herein, those in this section prevail unless stated otherwise. [0018] Whenever a group is described as being “optionally substituted” that group may be unsubstituted or substituted with one or more of the indicated substituents. Likewise, when a group is described as being “unsubstituted or substituted” if substituted, the substituent(s) may be selected from one or more of the indicated substituents. If no substituents are indicated, it is meant that the indicated “optionally substituted” or “substituted” group may be substituted with one or more group(s) (such as 1, 2 or 3 groups) individually and independently selected from deuterium, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, heteroaryl, heterocyclyl, aryl(alkyl), heteroaryl(alkyl), (heterocyclyl)alkyl, hydroxy, alkoxy, acyl, cyano, halogen, thiocarbonyl, O-carbamyl, N-carbamyl, O-thiocarbamyl, N-thiocarbamyl, C-amido, N-amido, S-sulfonamido, N-sulfonamido, C-carboxy, O-carboxy, isocyanato, thiocyanato, isothiocyanato, nitro, azido, silyl, sulfenyl, sulfinyl, sulfonyl, haloalkyl, haloalkoxy, trihalomethanesulfonyl, trihalomethanesulfonamido, an amino, a mono-substituted amine and a di-substituted amine. [0019] As used herein, “C a to C b ” in which “a” and “b” are integers refer to the number of carbon atoms in an alkyl, alkenyl or alkynyl group, or the number of carbon atoms in the ring of a cycloalkyl, cycloalkenyl, aryl, heteroaryl or heterocyclyl group. That is, the alkyl, alkenyl, alkynyl, ring of the cycloalkyl, ring of the cycloalkenyl, ring of the aryl, ring of the heteroaryl or ring of the heterocyclyl can contain from “a” to “b”, inclusive, carbon atoms. Thus, for example, a “C 1 to C 4 alkyl” group refers to all alkyl groups having from 1 to 4 carbons, that is, CH 3 -, CH 3 CH 2 -, CH 3 CH 2 CH 2 -, (CH 3 ) 2 CH-, CH 3 CH 2 CH 2 CH 2 -, CH 3 CH 2 CH(CH 3 )- and (CH 3 ) 3 C-. If no “a” and “b” are designated with regard to an alkyl, alkenyl, alkynyl, cycloalkyl cycloalkenyl, aryl, heteroaryl or heterocyclyl group, the broadest range described in these definitions is to be assumed. [0020] As used herein, “alkyl” refers to a straight or branched hydrocarbon chain that comprises a fully saturated (no double or triple bonds) hydrocarbon group. The alkyl group may have 1 to 20 carbon atoms (whenever it appears herein, a numerical range such as “1 to 20” refers to each integer in the given range; e.g., “1 to 20 carbon atoms” means that the alkyl group may consist of 1 carbon atom, 2 carbon atoms, 3 carbon atoms, etc., up to and including 20 carbon atoms, although the present definition also covers the occurrence of the term “alkyl” where no numerical range is designated). The alkyl group may also be a medium size alkyl having 1 to 10 carbon atoms. The alkyl group could also be a lower alkyl having 1 to 6 carbon atoms. The alkyl group of the compounds may be designated as “C 1 -C 4 alkyl” or similar designations. By way of example only, “C 1 -C 4 alkyl” indicates that there are one to four carbon atoms in the alkyl chain, i.e., the alkyl chain is selected from methyl, ethyl, propyl, iso-propyl, n-butyl, iso-butyl, sec-butyl and t-butyl. Typical alkyl groups include, but are in no way limited to, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tertiary butyl, pentyl and hexyl. The alkyl group may be substituted or unsubstituted.

Typical cycloalkyl groups include, but are in no way limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl and cyclooctyl. [0024] As used herein, “cycloalkenyl” refers to a mono- or multi- cyclic hydrocarbon ring system that contains one or more double bonds in at least one ring; although, if there is more than one, the double bonds cannot form a fully delocalized pi- electron system throughout all the rings (otherwise the group would be “aryl,” as defined herein). When composed of two or more rings, the rings may be connected together in a fused fashion. A cycloalkenyl can contain 3 to 10 atoms in the ring(s) or 3 to 8 atoms in the ring(s). A cycloalkenyl group may be unsubstituted or substituted. [0025] As used herein, “aryl” refers to a carbocyclic (all carbon) monocyclic or multicyclic aromatic ring system (including fused ring systems where two carbocyclic rings share a chemical bond) that has a fully delocalized pi-electron system throughout all the rings.

The number of atoms in the ring(s) of a heteroaryl group can vary. For example, the heteroaryl group can contain 4 to 14 atoms in the ring(s), 5 to 10 atoms in the ring(s) or 5 to 6 atoms in the ring(s). Furthermore, the term “heteroaryl” includes fused ring systems where two rings, such as at least one aryl ring and at least one heteroaryl ring, or at least two heteroaryl rings, share at least one chemical bond.

A heterocycle may optionally contain one or more unsaturated bonds situated in such a way, however, that a fully delocalized pi-electron system does not occur throughout all the rings. The number of atoms in the ring(s) of a heterocyclyl group can vary. For example, the heterocyclyl group can contain 4 to 14 atoms in the ring(s), 5 to 10 atoms in the ring(s) or 5 to 6 atoms in the ring(s). The heteroatom(s) is an element other than carbon including, but not limited to, oxygen, sulfur and nitrogen. A heterocycle may further contain one or more carbonyl or thiocarbonyl functionalities, so as to make the definition include oxo-systems and thio-systems such as lactams, lactones, cyclic imides, cyclic thioimides and cyclic carbamates. When composed of two or more rings, the rings may be joined together in a fused fashion. Additionally, any nitrogens in a heterocyclyl may be quaternized.

(including pharmaceutically acceptable salts thereof). Example A LCMS (Liquid chromatography/Mass spectrometry) [0376] The High Performance Liquid Chromatography (HPLC) measurement was performed using a LC pump, a diode-array (DAD) or a UV detector and a column as specified in the respective methods. If necessary, additional detectors were included (see table of methods below). Flow from the column was brought to the Mass Spectrometer (MS) which was configured with an atmospheric pressure ion source. It is within the knowledge of the skilled person to set the tune parameters (e.g. scanning range, dwell time) in order to obtain ions allowing the identification of the compound's nominal monoisotopic molecular weight (MW). Data acquisition was performed with appropriate software. Compounds are described by their experimental retention times (Rt) and ions. If not specified differently in the table of data, the reported molecular ion corresponds to the [M+H] + (protonated molecule) and/or [M-H]-(deprotonated molecule). In case the compound was not directly ionizable the type of adduct is specified (i.e. [M+NH 4 ] + , [M+Na] + , [M+HCOO]-, etc.). For molecules with multiple isotopic patterns (Br, CI), the reported value is the one obtained for the lowest isotope mass. All results were obtained with experimental uncertainties that are commonly associated with the method used.

Example C PDL1/PD1 Binding Assay [0400] Compounds to be tested were serially diluted in DMSO, and further diluted in assay buffer (25 mM Hepes pH 7.4, 150 mM NaCl, 0.005% Tween 20, BSA 0.01%). Diluted compounds were added to the wells with final concentration of DMSO at 1%. PDL1-6xHis protein was added to the wells, mixed well with compound. The plates were incubated for 30 min at room temperature. PD1-Fc-Avi-Biotin protein was added to the wells. Final concentration of PDL1 and PD1 protein is 0.3 nM and 2.5 nM, respectively. After a binding time of 30 min at room temperature, Anti-6xHis Acceptor beads (final concentration 20 ug/ml) were added to the wells, and the incubation continued for 1 h. Streptavidin Donor beads (final concentration 20 ug/mL) were added at reduced light. The plates were sealed with foil and incubated in the dark for additional 1 h or overnight before reading on an Envision reader. The IC 50 values were determined by fitting the curves using a four-parameter equation in Graphpad Prism 8. Example D PD-1/PD-L1 NFAT Reporter Assay [0401] Cellular activity of the compounds was assessed using a co-culture reporter assay in which TCR-mediated NFAT activity of Jurkat T cells is constitutively inhibited by the engagement of PD-1 by PD-L1 expressing CHO cells. Blocking the PD-1/ PD-L1 interaction will release the inhibitory signal and results in TCR signaling and NFAT- mediated luciferase activity. [0402] CHO cells expressing surface-bound anti-CD3 antibodies and PD-L1 were first seeded overnight and treated with the compounds. Jurkat cells overexpressing PD-1 and a luciferase construct under NFAT promoter were then immediately seeded on the monolayer of CHO cells. The co-culture was then incubated for 6 hrs at 37 °C. Luciferase activity was assessed by adding the ONE-Glo reagent and measuring luminescence with a plate reader. EC 50 values were determined from the fit of the dose-response curves. [0403] Compounds described herein, as exemplified in the Examples, showed EC 50 or IC 50 values in the following ranges: A: IC 50 or EC 50 ^10 nM; B: 10 nM < IC 50 or EC 50 ^100 nM; C: 100 nM < IC 50 or EC 50 ^1000 nM; D : 1000 nM < IC 50 or EC 50 ^10000 nM; E : IC 50 or EC 50 > 10000 nM; F: IC 50 or EC 50 > 5000 nM; n.d. = not determined; n.r. = EC 50 not reached in the range of tested concentrations starting from 1 nM to 10000 nM.
