  Synthesis and antitumor activity of cis-dichloroplatinum(II) complexes of 1-(2-aminophenyl)-1,2,3,4-tetrahydroisoquinolines

  摘要：

  Fifteen cis-dichloroplatinum complexes (5a-5o) were synthesized by treatment of 1-(2-aminophenyl)-1,2,3,4-THIQs (4a-4o) with K2PtCl4. The antitumor activity of these compounds was examined against four different human tumor cell lines. Their structure-activity relationships for antitumor activity are reported. All of these compounds exhibited activity against MCF-7 cell line and showed good activity against WiDr cell line except 5c and 5f On the other hand, compounds 5j and 5o are more active than the other compounds against Hepa59T/VGH cell line. The electron-donating group at the 6-position of isoquinoline ring seems to decrease the antitumor activity and the chloro substituent at the C-4 position of the aniline ring shown the highest potency. The "trans influence" dominates the control of the stability of [1-(2-aminophenyl)1,2,3,4-THIQ]dichloroplatinums(II). (c) 2006 Elsevier SAS. All rights reserved.

• Unprecedented SnCl₂-Mediated Cyclization of Nitro Arenes via N−N Bond Formation

  A mild, efficient, one-pot protocol for the cyclization of nitro-aryl substrates using SnCl2 has been described. The mechanistic course of the reaction suggests the involvement of a hydroxylamine intermediate leading to an intramolecular cyclization via N-N bond formation. The versatility of the methodology has been demonstrated by using two nitro-aryl substrates derived from dihydroisoquinolines and dihydro-beta-carbolines. The intramolecular cyclization led to the formation of indazoles in high yields and purities.
