Potent small molecule Hedgehog agonists induce VEGF expression in vitro
摘要:
Here, we describe the synthesis, SAR studies as well as biological investigations of the known Hedgehog signaling agonist SAG and a small library of its analogues. The SAG and its derivatives were analyzed for their potency to activate the expression of the Hh target gene Gli1 in a reporter gene assay. By analyzing SAR important molecular descriptors for Gill activation have been identified. SAG as well as compound 10c proven to be potent activators of VEGF expression in cultivated dermal fibroblasts. Importantly and in contrast to SAG, derivative 10c displayed no toxicity in concentrations up to 250 mu m. (C) 2012 Elsevier Ltd. All rights reserved.

Vasopressin 1b (V1b) antagonists have been postulated as possible treatments for depression and anxiety. A novel series of potent and selective V1b antagonists has been identified starting from an in-house screen hit. The incorporation of a sulfonamide linker between a tetrahydroisoquinoline core and amino piperidine lead to the identification of a V1b antagonist with similar affinity for human and rat receptors. Further optimization of the right hand portion afforded potent V1b antagonists that possessed moderate to high selectivity over other receptors. (C) 2009 Elsevier Ltd. All rights reserved.
