beta carboline/sarcoma

A series of novel N⁹-heterobivalent β-carbolines has been synthesized. All the novel compounds were tested for their anticancer activity against six tumour cell lines in vitro. Among these molecules, compounds 5b, and 5w exhibited strong cytotoxic activities with IC₅₀ value of

A series of N-acylhydrazone-linked, heterobivalent β-carboline derivatives was designed and synthesized from l-tryptophan in a nine-step reaction sequence. The effort resulted in the heterobivalent β-carbolines 10a-t in good yields. The target compounds were characterized by ¹H NMR,

We synthesized 47 kinds of 3-amino- or 3-benzylamino-β-carboline derivatives with a substituent on the 6-, 8-, or 6,8-carbon atoms and evaluated their antitumor activities for Hela S-3 and Sarcoma 180 cell lines using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay.

Ecteinascidins (Ets), isolated from the Caribbean tunicate Ecteinascidia turbinata, protect mice in vivo against P388 lymphoma, B16 melanoma, M5076 ovarian sarcoma, Lewis lung carcinoma, and the LX-1 human lung and MX-1 human mammary carcinoma xenografts. Crystal structures of two
