Abstract

Official abstract text for this publication.

Compounds and pharmaceutical compositions that down-regulate immune checkpoints such as PD-1, PD-L1 and CTLA-4 are provided. Also provided are methods of treating a disease by down-regulating immune checkpoints such as PD-1, PD-L1 and CTLA-4. The methods are useful for treating cancer and viral infection in a subject.

First claim

Opening claim text (preview).

What is claimed is: 1. A compound selected from the group consisting of: 4-fluoro-2-(5-nitro-1H-benzo[d]imidazol-2-yl)phenol; 6-chloro-2-(trifluoromethyl)-N-(4-(trifluoromethyl)phenyl)-1H-benzo[d]imidazole-4-carboxamide; and 4-chloro-2-(5-(4-nitrophenyl)-4H-1,2,4-triazol-3-yl)phenol, or a pharmaceutically acceptable salt thereof. 2. A pharmaceutical composition comprising at least one pharmaceutically acceptable carrier and an effective amount of a compound of claim 1 or a pharmaceutically acceptable salt thereof. 3. The compound of claim 1 , wherein the compound is 6-chloro-2-(trifluoromethyl)-N-(4-(trifluoromethyl)phenyl)-1H-benzo[d]imidazole-4-carboxamide, or a pharmaceutically acceptable salt thereof. 4.
