Privileged fragment-based design, synthesis and in vitro antitumor activity of imatinib analogues

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Synthesis of novel psoralen analogues and their in vitro antitumor activity.

New tetracyclic benzofurocoumarin (benzopsoralen) analogues were synthesized and their inhibitory effect on the growth of tumor cell lines was evaluated. The human tumor cell lines used were MDA MB231 (breast adenocarcinoma), HeLa (cervix adenocarcinoma) and TCC-SUP (bladder transitional cell carcinoma). The in vitro antitumor activity of the new benzopsoralens was discussed in terms of structu...

design, synthesis, and acetylcholinesterase inhibitory activity of novel coumarin analogues

Synthesis and antitumor activity of mechercharmycin A analogues.

Several analogues of the cytotoxic thiopeptide IB-01211 or mechercharmycin A (1) have been synthesized. The cytotoxicity of 1 and the synthesized analogues were evaluated against a panel of three human tumor cell lines. Thiopeptide 1 and the most active derivatives 2 and 3c were chosen for further studies on effects on cell cycle progression and induction of apoptosis. Interestingly, the inhibi...

Synthesis and antitumor activity of inositol phosphotriester analogues.

Inositol phosphates, as important second messengers of signal transduction, regulate many biological functions. However, cell penetration and phospholipase stability could be two main issues faced by inositol phosphate analogues used as lead compounds for drug discovery. Inositol phosphotriester analogues could be more beneficial to diffuse across plasma membrane. In this paper, we describe the...
