Synthesis of potent MDA-MB 231 breast cancer drug molecules from single step.

We have prepared novel potent breast cancer drug molecules from non-toxic and inexpensive method. Column chromatography is not necessary for purification of target molecules. The value of overall atom economy, environmental factor, environmental catalyst and product mass intensity gives additional merits for this synthetic method.

Discovery of Novel Dimeric Pyridinium Bromide Analogues Inhibits Cancer Cell Growth by Activating Caspases and Downregulating Bcl-2 Protein.

Flexible dimeric substituted pyridinium bromides with primary and tertiary amines are prepared by conventional and solvent-free methods. The formation of compounds and is much easier than that of compounds and because of the benzyl carbon which is more electropositive than the primary alkyl carbon. The newly synthesized dimeric pyridinium compounds are optimized using DFT and B3LYP 6-31 g(d,p).

Organic solvents can influence acetylcholine neurotransmission in .

Background: Identification of novel drugs by bio-prospecting natural products like various parts of the plants, or other extracts and drug discovery requires differential fractionation with various organic solvents followed by their concentration through evaporation under nitrogen gas, which is a standard practice.

Purpose: Determination of contribution of vehicle control of organic solvents (chloroform, ethanol, ethyl acetate and n-hexane) processed in the similar manner in the modulation of acetylcholine(ACh) neurotransmission in , Aldicarb induced paralysis assay.

Methods: The organic solvents concentrated as described in background was used to identify their contribution in ACh modulation through ACh esterase inhibitor, Aldicarb, treatment of , which leads to time dependent paralysis of the worms.

Cardioprotective effect of Nerium oleander flower against isoproterenol-induced myocardial oxidative stress in experimental rats.

Nerium oleander Linn (NOL) an evergreen shrub belonging to the Apocynaceae family has been reported to have a wide spectrum of bioactivities. In in vitro study, the free radical scavenging potential of the hydroethanolic extract of N oleander Linn (ENO) flower and its fractions (glycosidic and nonglycosidic) were studied using 2, 2(')-azino-di [3-ethylbenzthiazoline sulphonate] (ABTS(*+) ) and 1, 1-diphenyl-2-picrylhydrazyl (DPPH*) scavenging assay. ENO exhibited better radical scavenging activities than its fractions.
