Article Title: Potent small molecule Hedgehog agonists induce VEGF expression in vitro.
Article Snippet: 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 Gli1 activation have been identified.

Cell Culture:

Article Title: Synthesis and evaluation of caged Garcinia xanthones.
Article Snippet: Inspired by the combination of unique structure and potent bioactivities exhibited by several family members of the caged Garcinia xanthones, we developed a synthesis of simplified analogues that maintain the overall caged motif.. The caged structure of these compounds was constructed via a site-selective Claisen/Diels–Alder reaction cascade.. We found that the fully substituted caged structure, in which are included the C18 and C23 geminal methyl groups, is necessary to maintain bioactivity.

Article Title: Indeno[1,2-d]pyrido[1,2-a]pyrimidines: a new class of receptor tyrosine kinase inhibitors.
Article Snippet: Receptor tyrosine kinases (RTKs) are important mediators of signal transduction and play critical roles in cell growth, differentiation, metabolism, and apoptosis, and are deeply involved in oncogenesis.. Binding of growth factors to the extracellular domains of RTKs leads to their dimerization, resulting in activation of the intracellular kinase domain, which eventually enables autophosphorylation at specific tyrosine residues.. This family is also represented in oncogenic fusion proteins such as the Bcr-Abl protein of the Philadelphia chromosome.
