Synthesis of different heterocycles-linked chalcone conjugates as cytotoxic agents and tubulin polymerization inhibitors

A series of new heterocycles-linked chalcone conjugates has been designed and synthesized by varying different alkane spacers. These conjugates were tested for their in vitro cytotoxic potential against a panel of selected human cancer cell lines namely,

Development of a novel nitric oxide (NO) production inhibitor with potential therapeutic effect on chronic inflammation

Inflammation is a complex biological response to stimuli. Activated macrophages induced excessively release of pro-inflammatory cytokines and mediators such as endogenous radical nitric oxide (NO) play a significant role in the progression of multiple inflammatory diseases. Both natural and synthetic chalcones possess a wide range of bioactivities. In this work, thirty-nine chalcones and three related compounds, including several novel ones, based on bioactive kava chalcones were designed, synthesized and their inhibitory effects on NO production in RAW 264.7 cells were evaluated. The novel compound (E)-1-(2′-hydroxy-4′,6′-dimethoxyphenyl)-3-(3-methoxy-4-(3-morpholinopropoxy)phenyl)prop-2-en-1-one (53) exhibited a better inhibitory activity (84.0%) on NO production at 10 μM (IC50 = 6.4 μM) with the lowest cytotoxicity (IC50 > 80 μM) among the tested compounds. Besides, western blot analysis indicated that compound 53 was a potent down-regulator of inducible nitric oxide synthase (iNOS) protein. Docking study revealed that compound 53 also can dock into the active site of iNOS. Furthermore, at the dose of 10 mg/kg/day, compound 53 could both significantly suppress the progression of inflammation on collagen-induced arthritis (CIA) and adjuvant-induced arthritis (AIA) models. In addition, the structure-activity relationship (SAR) of the kava chalcones based analogs was also depicted.

Design and synthesis of 4′-O-alkylamino-tethered-benzylideneindolin-2-ones as potent cytotoxic and apoptosis inducing agents

A series of new 4′-O-alkylamino-tethered-benzylideneindolin-2-one derivatives has been synthesized and evaluated for their anti-proliferative activity against selected human cancer cell lines of lung (A549), prostate (DU-145), breast (BT549 and MDA-MB-231) and normal breast epithelial cells (MCF-10A). Gratifyingly, the compounds 5j, 5o and 5r exhibited potent cytotoxicity against breast cancer cell lines (BT549 and MDA-MB-231) with IC50values in the range of 1.26–2.77?μM, and are found to be safer with lesser cytotoxicity on normal breast epithelial cells (MCF-10A). Further, experiments were conducted with these compounds 5j, 5o and 5r on MDA-MB-231 cancer cells to study the mechanism of growth inhibition and apoptosis inducing effect. Treatment of MDA-MB-231 cells with test compounds resulted in inhibition of cell migration through disorganization and disruption of F-actin capping protein. The flow-cytometry analysis results showed that the compound 5o arrested MDA-MB-231 cells in G0/G1 phase of cell cycle in a dose dependent manner. Hoechst staining study revealed that the test compounds inhibited tumor cell proliferation through induction of apoptosis. In addition, the mitochondrial membrane potential (DΨm) was affected and the increased level of reactive oxygen species (ROS) was noted in MDA-MB-231 cells.

Design, synthesis, and anticancer evaluation of long-chain alkoxylated mono-carbonyl analogues of curcumin

Curcumin is a nontoxic phenolic compound that modulates the activity of several cellular targets that have been linked with cancers and other chronic diseases. However, the efficacy of curcumin in the clinic has been limited by its poor bioavailability an

Synthesis, antimalarial activity and cytotoxic potential of new monocarbonyl analogues of curcumin

A series of novel monocarbonyl analogues of curcumin have been designed, synthesized and tested for their activity against Molt4, HeLa, PC3, DU145 and KB cancer cell lines. Six of the analogues showed potent cytotoxicity towards these cell lines with IC50 values below 1 μM, which is better than doxorubicin, a US FDA approved drug. Several analogues were also found to be active against both CQ-resistant (W2 clone) and CQ-sensitive (D6) strains of Plasmodium falciparum in an in-vitro antimalarial screening. This level of activity warrants further investigation of the compounds for development as anticancer and antimalarial agents.

One-pot conversion of 2-nitrobenzonitriles to quinazolin-4(3H)-ones and synthesis of gefitinib and erlotinib hydrochloride

A simple and efficient one-pot conversion of 2-nitrobenzonitriles to quinazolin-4(3H)-ones involving reduction, formylation, hydrolysis and cyclization is reported. These quinazolinones have been used for making in economical way the anticancer drug molecules gefitinib (Iressa) and erlotinib HCl (Tarceva).
