Pin1 is a peptidyl prolyl cis-trans isomerase (PPIase) and inhibiting Pin1 is a potential way for discovering anti-tumor agents. With an aim to find potent Pin1 inhibitors with a novel scaffold, a series of thiazole derivatives with an alicyclic heterocycles on the 2-position were designed, synthesized and tested against human Pin1. Compound 9p bearing a 2-oxa-6-azaspiro [3,3] heptane moiety on the thiazole scaffold was identified as the most potent Pin1 inhibitor of this series with an IC50 value of 0.95 μM. The structure-activity relationship (SAR) and molecular modeling study indicated that introducing an alicyclic ring with an H-bond acceptor would be a viable way to improve the binding affinity.

Glycogen phosphorylase (GP), which plays a crucial role in the conversion of glycogen to glucose-1-phosphate, is a target for therapeutic intervention in diabetes. In this study, we report the design and synthesis of 29 new derivatives of 2-oxo-1,2-dihydro pyridin-3-yl amides, as potential inhibitors of GP. The hit rate (45%) was high with 13 compounds inhibiting GPa (between 33% at 4.40 mM and an IC50 of 1.92 μM). Two lead compounds were identified as compounds exhibiting good GPa inhibition (IC50 = 2.1 and 1.92 μM). SAR analysis of these compounds revealed sensitivity of GPa to the length of the 2-oxo-1,2-dihydro pyridin-3-yl amide derivative and a preference for inclusion of a 3,4-dichlorobenzyl moiety.

Cryptosporidium inosine 5′-monophosphate dehydrogenase (CpIMPDH) has emerged as a therapeutic target for treating Cryptosporidium parasites because it catalyzes a critical step in guanine nucleotide biosynthesis. A 4-oxo-[1]benzopyrano[4,3-c]pyrazole derivative was identified as a moderately potent (IC50 = 1.5 μM) inhibitor of CpIMPDH. We report a SAR study for this compound series resulting in 8k (IC50 = 20 ± 4 nM). In addition, an X-ray crystal structure of CpIMPDH·IMP·8k is also presented.

Cryptosporidium parasites are important waterborne pathogens of both humans and animals. The Cryptosporidium parvum and Cryptosporidium hominis genomes indicate that the only route to guanine nucleotides is via inosine 5′-monophosphate dehydrogenase (IMPDH). Thus the inhibition of the parasite IMPDH presents a potential strategy for treating Cryptosporidium infections. A selective benzimidazole-based inhibitor of C. parvum IMPDH (CpIMPDH) was previously identified in a high throughput screen. Here we report a structure-activity relationship study of benzimidazole-based compounds that resulted in potent and selective inhibitors of CpIMPDH. Several compounds display potent antiparasitic activity in vitro.

A new series of 1,3-dipropyl-8-(1-phenylacetamide-1H-pyrazol-3-yl)-xanthine derivatives has been identified as potent A2B adenosine receptor antagonists. The products have been evaluated for their binding affinities for the human A2B, A1, A2A, and A3 adenosine receptors. N-(4-chloro-phenyl)-2-[3-(2,6-dioxo-1,3-dipropyl-2,3,6,7-tetrahydro-1H-purin-8-yl)-5-methyl-pyrazol-1-yl] (11c) showed a high affinity for the human A2B adenosine receptor Ki = 7 nM and good selectivity (A1, A2A, A3/A2B > 140). Synthesis and SAR of this novel class of compounds is presented herein.
