Synthesis of spirooxindoles via asymmetric 1,3-dipolar cycloaddition
摘要:
An efficient method was developed for the asymmetric synthesis of 2'-alkyl-4'aryl-1H-spiro[indole-3,3'-pyrrolidin]-2-ones, which are potential inhibitors of the p53-MDM2 interaction. Our X-ray crystallographic analysis revealed that this 1,3-dipolar cycloaddition proceeds with high stereoselectivity but differently from previously published results. (c) 2005 Elsevier Ltd.

aim of improving its potency and physicochemicalprofile. The 6‐fluorobenzylideneindolinone 3‐12 bearing a 3′‐N‐propylaminosulfonyl substituent was found to be a promising substitute. Compound 3‐12 [6‐fluoro‐3‐(3′‐N‐propylaminosulfonylbenzylidene)‐1,3‐dihydroindol‐2‐one] was found to be tenfold more soluble than 4 and to have sub‐micromolar growthinhibitoryactivities on HCC cells. It is apoptogenic

The present invention relates generally to organic chemistry, biochemistry, pharmacology and medicine. More particularly, it relates to 3-benzylidene-indolin-2-one derivatives and their physiologically acceptable salts and prodrugs which modulate the activity of protein kinases ("PKs"), especially protein tyrosine kinase, and, therefore, are expected to exhibit a salutary effect against disorders related to abnormal PK activity. The present invention is further directed to methods of using of these compounds, alone or in combination with other therapeutic agents, for the alleviation, prevention and/or treatment of protein kinase-mediated diseases and disorders, such as cancer.
