Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures.

Indoleamine 2,3-dioxygenase (IDO1) inhibitors are speculated to be useful in cancer immunotherapy, but a phase III clin. trial of the most advanced IDO1 inhibitor, epacadostat, did not meet its primary endpoint and was abandoned. In previous work we identified the novel IDO1 inhibitor N-(4-chlorophenyl)-2-((5-phenylthiazolo[2,3-c][1,2,4]triazol-3-yl)thio)acetamide 1 through high-throughput screening (HTS). Herein, we report a structure-activity relationship (SAR) study of this compound, which resulted in the potent IDO1 inhibitor 1-(4-cyanophenyl)-3-(3-(cyclopropylethynyl)imidazo[2,1-b]thiazol-5-yl)thiourea 47 (hIDO IC50 = 16.4 nM). X-ray co-crystal structural anal. revealed that the basis for this high potency is a unique sulfur-aromatic interaction network formed by the thiourea moiety of 47 with the F163 and F226. This finding is expected to inspire new approaches towards the discovery of potent IDO1 inhibitors in the future.
After consulting a lot of data, we found that this compound(65705-44-4)Related Products of 65705-44-4 can be used in many types of reactions. And in most cases, this compound has more advantages.
