Selected novel 5’-amino-2’-hydroxy-1, 3-diaryl-2- propen-1-ones arrest cell cycle of HCT-116 in G0/G1 phase

A series of 5’-amino-2’-hydroxy-1,3-diaryl-2-propen-1-ones (AC1-AC15) were synthesized by Claisen-Schmidt condensation of 5'-acetamido-2’-hydroxy acetophenone with various substituted aromatic aldehydes. The syn- thesized compounds were characterized by FTIR, 1H NMR and mass spectrometry and evaluated for their selec- tive cytotoxicity using MTT assay on two cancer cell lines namely breast cancer cell line (MCF-7), colon cancer cell line (HCT-116) and one normal kidney epithelial cell line (Vero). Among the tested compounds, AC-10 showed maximum cytotoxic effect on MCF-7 cell line with IC50 value 74.7 ± 3.5 μM. On HCT-116 cells, AC-13 exhibited maximum cytotoxicity with IC50 value 42.1 ± 4.0 μM followed by AC-14 and AC-10 with IC50 values 62 ± 2.3 μM and 95.4 ± 1.7 μM respectively. All tested compounds were found to be safe on Vero cell line with IC50 value more than 200 μM. Based on their highest efficacy on HCT-116, AC-10, AC-13 and AC-14 were selected for mechanistic study on this cell line by evaluating changes nucleomorphological characteristics using acridine orange-ethidium bromide (AOEB) dual stain and by analyzing cell cycle with flow cytometry using propidium iodide stain. In AOEB staining, all three tested compounds showed significant (p 0/G1 phase and by AC-13 in G0/G1 and G2/M phase. The study reflected the potential of AC-10, AC-13 and AC-14 to be the lead molecules for further optimization.

Synthesis and anti-cancer activity of novel thiazolidinone analogs of 6-aminoflavone

Novel heterocyclic analogs were synthesized by combining a flavone nucleus and thiazolidinone ring in an effort to potentiate the existing anti-cancer activity of flavone. The syntheses of 6-aminoflavone, 6-amino-3-methoxyflavone, 6-amino-3-methoxy-3',4'-dimethxyflavone and their corresponding thiazolidinone analogs were performed. Fifteen novel analogs were synthesized and evaluated for their anti-cancer activity using cell-based assay techniques and in vivo testing. As expected, the analogs improved cytotoxicity and were shown to increase the life span of cancer-bearing mice. Cytotoxicity was evaluated using 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assays in HeLa, MDA-MB-435, and Vero cell lines. In vivo evaluation of anti-cancer activity performed in albino mice bearing Dalton's ascites carcinoma showed that the new analogs enhanced life span and prevented increases in body weight owing to tumor volumes. Moreover, cell-cycle analysis and Hoechst staining analysis proved the apoptotic potential of these analogs. Preliminary pharmacokinetic evaluation was carried out on the synthesized compounds to determine the lipophilicity and pKa. Lipophilicity was determined using high-performance liquid chromatography and the results showed a direct correlation between the observed anti-cancer activity and log P value, while pKa values indicated the ionizing range which is a prediction tool for solubility and permeability.

Synthesis of some new 6-amino-3-methoxyflavones

Several naturally occurring flavones having 3-methoxy group are known for their biological activities. Here we report the synthesis of some new flavones starting from 5-acetamido-2-hydroxyacetophenone.
