A series of urea derivatives bearing nitroaryl moiety has been synthesized and assayed for their potential antiproliferative activities. Some of the tested compounds displayed activity in RK33 laryngeal cancer cells and TE671 rhabdomyosarcoma cells while being generally less toxic to healthy HSF human fibroblasts cells. One compound was demonstrated to be a moderate CDK2 inhibitor with IC50 = 14.3 μM. Its structure was solved by an X-ray crystallography and molecular modelling was performed to determine structure-activity relationship. Obtained compounds constitute novel structures and generally demonstrated greater cytotoxicity in comparison to cisplatin. This study offers new structural motifs with potential for further development.

Small molecule inhibitors of the HIV-1 nucleocapsid protein (NC) are considered as promising agents in the treatment of HIV/AIDS. In an effort to exploit the privileged 2-amino-4-phenylthiazole moiety in NC inhibition, here we conceived, synthesized, and tested in vitro 18 NC inhibitors (NCIs) bearing a double functionalization. In these NCIs, one part of the molecule is deputed to interact noncovalently with the NC hydrophobic pocket, while the second portion is designed to interact with the N-terminal domain of NC. This binding hypothesis was verified by molecular dynamics simulations, while the linkage between these two pharmacophores was found to enhance antiretroviral activity both on the wild-type virus and on HIV-1 strains with resistance to currently licensed drugs. The two most interesting compounds 6 and 13 showed no cytotoxicity, thus becoming valuable leads for further investigations.

In an effort to identify new antidiabetic agents, we have discovered a novel family of (5-imidazol-2-yl-4-phenylpyrimidin-2-yl)[2-(2-pyridylamino)ethyl]amine analogues which are inhibitors of human glycogen synthase kinase 3 (GSK3). We developed efficient synthetic routes to explore a wide variety of substitution patterns and convergently access a diverse array of analogues. Compound 1 (CHIR-911, CT-99021, or CHIR-73911) emerged from an exploration of heterocycles at the C-5 position, phenyl groups at C-4, and a variety of differently substituted linker and aminopyridine moieties attached at the C-2 position. These compounds exhibited GSK3 IC50s in the low nanomolar range and excellent selectivity. They activate glycogen synthase in insulin receptor-expressing CHO-IR cells and primary rat hepatocytes. Evaluation of lead compounds 1 and 2 (CHIR-611 or CT-98014) in rodent models of type 2 diabetes revealed that single oral doses lowered hyperglycemia within 60 min, enhanced insulin-stimulated glucose transport, and improved glucose disposal without increasing insulin levels.

This report describes the synthesis and pharmacological evaluation of a series of novel potassium channel openers related to the pinacidil-type compounds. Thioureas, cyanoguanidines, and pyridine N-oxides were systematically evaluated for their effects on both the inhibition of spontaneous mechanical activity in rat portal vein (in vitro) and their antihypertensive activity (in vivo), and the structure-activity relationship for this series of compounds was discussed. Good correlation between in vitro and iv antihypertensive activity was observed for these compounds. Among them, cyanoguanidines bearing a conformationally rigid unit such as a norbornyl group generally possessed potent activity in both in vitro and in vivo studies. Especially, N-(6-amino-3-pyridyl)-N'-cyano-N''-(1-methyl-2- norbornyl)guanidine (23d) was identified as a more potent potassium channel opener in vitro (EC100 = 3 x 10-8 M) than pinacidil (EC100 = 10-7 M).
