8-THP-DHI analogs as potent Type I dual TIE-2/VEGF-R2 receptor tyrosine kinase inhibitors
摘要:
A novel series of 8-(2-tetrahydropyranyl)-12,13-dihydroindazolo[5,4-a] pyrrolo[3,4-c]carbazoles (THP-DHI) was synthesized and evaluated as dual TIE-2 and VEGF-R2 receptor tyrosine kinase inhibitors. Development of the structure-activity relationships (SAR) with the support of X-ray crystallography led to identification of 7f and 7g as potent, selective dual TIE-2/VEGF-R2 inhibitors with excellent cellular potency and acceptable pharmacokinetic properties. Compounds 7f and 7g were orally active in tumor models with no observed toxicity. (C) 2010 Elsevier Ltd. All rights reserved.

The present invention relates to a method for regioselectively reducing the maleimide compounds of formula (I). The invention also relates to C7 hydroxy lactam regioisomers of formula (II) obtainable by this method and their use for the preparation of lactams of formula (Ill) which are particularly useful as intermediate for the synthesis of fused pyrrolocarbazoles.
