Synthesis and cytotoxic activity of novel 2,6-disubstituted-4-mor-pholinothieno[3,2-d]pyrimidines as potent anti-tumor agents
摘要:
A series of 2,6-disubstituted-4-morpholinothieno[3,2-d]pyrimidine derivatives were synthesized and their cytotoxic activity against H460, HT-29, MDA-MB-231, U87MG and H1975 cancer cell lines were evaluated in vitro Most of the target compounds exhibited moderate to excellent activity to the tested cell lines. The most promising compound 23 (0.84 mu mol/L, 0.23 mu mol/L, 2.52 mu mol/L, 1.80 mu mol/L) was 1.0, 2.9, 29.3 and 4.3 times more active than GDC-0941 (0.87 mu mol/L, 0.66 mu mol/L, 73.8 mu mol/L, 7.77 mu mol/L) against H460, HT-29, MDA-MB-231 and U87MG cell lines, respectively.

to develop potent antitumor agents, a series of novel 2‐hydrazonylpyrido[2,3‐b]pyrazin‐3(4H)‐one derivatives were designed and synthesized. All the prepared compounds were screened for their cytotoxic activities against A549, MDA‐MB‐231 and HT‐29 cell lines in vitro. Pharmacological data indicated that five of the target compounds showed cytotoxicity against A549 cell line below a concentration of

Lysophosphatidic acid acyltransferase-beta (LPAAT-β) catalyzes the production of phosphatidic acid (PA) from lysophosphatidic acid (LPA). The lipid cofactor PA contributes to the activation of c-Raf, BRAF, mTOR and PKC-ζ. LPAAT-β expression is a prognostic factor in gynecologic malignancies and is being investigated as a therapeutic target in a variety of tumor types. A class of thiosemicarbazones was identified as inhibitors of LPAAT-β from a screen of a library of small molecules. A focused library of thiosemicarbazones derivatives was prepared and led to the development of compounds which potently inhibit LPAAT-β and inhibit the growth of MiaPaCa2 human pancreatic cancer cells.
