Design, synthesis and structure-activity relationship studies of a novel focused library of 2,3,4-substituted oxazolidines with antiproliferative activity against cancer cell lines

In the present work we describe the synthesis and antiproliferative evaluation of a focused library of 30 novel oxazolidines designed by modification of N-substituent, by ring variation, by alkyl variation or by extension of the structure. It was noted that carbamate and N,O-aminal groups were essential for activity. In general, replacement of the phenyl ring with pyridinyl was not tolerated. However, the introduction of a second phenyl ring with an appropriate spacer at the 3- or 4-position of the first phenyl ring generally enhanced the cytotoxic profile. Among all the prepared compounds, 24 was the most potent compound found in this class, being active on four of five cancer cell lines and it was 5-fold and 10-fold more potent than the lead compounds against HL60 and JURKAT cells, respectively. In addition, it showed relevant activity against MCF-7 and HCT-116 cells, which were resistant to lead. Moreover, 24 showed little antiproliferative activity against VERO, indicating low toxicity to normal cells. Thus, this compound has the potential to be developed as an anticancer agent.

In vitro antitumor evaluation of some new tetra substituted 1,2,4-triazines

A new series of tetra substituted 1,2,4-triazines (4, 5, 7 and 8) was synthesized via the reaction of 3,1-oxazolinone (1) with thiosemicarbazide to give 6-hydroxy-5-(p-hydroxybenzylidene)-3-phenyl-2-(amino) thioxo-1,2,4-triazine (3). Treatment of 1,2,4-triazine derivative 3 with carbon disulphide and p-chlorophenacyl bromide yielded the corresponding 1,2,4-triazine derivatives 4 and 7. Acetylation of tetra-substituted 1,2,4-tri-azines 4 and 7 with acetic anhydride gave tri acetyl and di acetyl derivatives 5 and 8. Compounds structure was confirmed by IR,1H,13C-NMR, MS, and elemental analysis. The cytotoxic activities of some synthesized, 1,2,4-triazines were evaluated on human hepatocellular carcinoma cells (HepG-2) and human colon carcinoma cells (HCT-116) using the MTT method. We found that, compounds 5 (IC50 = 3.60 mug/mL) and 8 (IC50 = 4.40 mug/mL) have better activity against HCT-116 cell line than the reference doxorubcin (IC50 = 5.30 mug/mL), while compound 7 has best activity against HepG-2 cell line.

Isolation, biological activity evaluation, structure elucidation, and total synthesis of eliamid: A novel complex i inhibitor

Eliamid is a secondary metabolite isolated from two bacterial strains. This molecule features a linear polyketide backbone terminated by a tetramic acid amide moiety. Among other biological activities, eliamid shows a high and specific cytostatic action on human lymphoma and cervix carcinoma cell lines. The 2,4-anti relative configuration of the C-2,C-4-dimethyl substituted amide fragment was assigned by means of Breit’s rule. The absolute configuration of all stereocenters was determined by a combination of degradation methods, structural similarity analysis and total synthesis. The stereogenic centers were introduced by vinylogous Mukaiyama aldol reaction and two consecutive Myers alkylations. The use of pentafluorophenyl ester as acylation agent allowed the efficient formation of tetramic acid amide. The longest linear sequence in the synthesis consist of 13 steps and proceeds with 12 % overall yield. Differential spectroscopy experiments with beef heart submitochondrial particles established that eliamid is a potent inhibitor of the NADH-ubiquinone oxidoreductase complex. Additionally, biosynthesis of eliamid was investigated by feeding experiments with 13C-labeled precursors. How valuable is Breit’s rule? Isolation, biological activity profiling, structure elucidation and total synthesis of polyketide natural product eliamid are reported. This molecule is characterized by a tetramic acid amide fragment, which is rather rare among secondary metabolites isolated from myxobacteria. Copyright
