Synthesis and biological evaluation of 3-phenyl-3-aryl carboxamido propanoic acid derivatives as small molecule inhibitors of retinoic acid 4-hydroxylase (CYP26A1)
摘要:
All-trans-retinoic acid (ATRA), the biologically active metabolite of vitamin A, is used medicinally for the treatment of hyperproliferative diseases and cancers. However, it is easily metabolized. In this study, the leading compound S8 was found based on virtual screening. To improve the activity of the leading compound S8, a series of novel S8 derivatives were designed, synthesized and evaluated for their in vitro biological activities.All of the prepared compounds showed that substituting the 5-chloro-3-methyl-1-phenyl-1H-pyrazole group for the 2-tertbutyl-5-methylfuran scaffold led to a clear increase in the biological activity. The most promising compound 32, with a CYP26A1 IC50 value of 1.36 mu M (compared to liarozole (IC50 = 2.45 mu M) and S8 (IC50 = 3.21 mu M)) displayed strong inhibitory and differentiation activity against HL60 cells. In addition, the study focused on the effect of beta-phenylalanine, which forms the coordination bond with the heme of CYP26A1. These studies suggest that the compound 32 can be used as an appropriate candidate for future development. (C) 2014 Elsevier Ltd. All rights reserved.
Design and synthesis of novel potent and selective integrin αvβ3 antagonists—Novel synthetic routes to isoquinolinone, benzoxazinone, and quinazolinone acetates
An unexpected ring contraction of benzazepinone based alpha(nu)beta(3) antagonists led to the design of quinolinone-type derivatives. Novel and efficient syntheticroutes to isoquinolinone, benzoxazinone, and quinazolinone acetates were established. Nanomolar alpha(nu)beta(3) antagonists based on these new scaffolds were prepared. Moreover, benzoxazinones 15a and 15b exhibited high microsomal stability

Synthesis, in Vitro and in Vivo Biological Evaluation, and Comprehensive Understanding of Structure−Activity Relationships of Dipeptidyl Boronic Acid Proteasome Inhibitors Constructed from β-Amino Acids
An extensive structure-activity relationship (SAR) study of 72 dipeptidyl boronic acid proteasome inhibitors constructed from beta-amino acids is reported. SAR analysis revealed that bicyclic groups at the RI position, 3-F substituents at the R-2 position, and bulky aliphatic groups at the R-3 position were favorable to the activities. Enzymatic screening results showed that compound 78, comprising all of these features, was the most active inhibitor against the 20S human proteasome at less than a 2 nM level, as active as the marketed drug bortezomib. Cellular assays confirmed that compound 78 was the most potent against two hematologic and some solid tumor cells with IC50 values less than 1 mu M. Pharmacokinetic profiles suggested that 78 showed higher plasma exposure and a longer half-life than bortezomib.
