Abstract This work aims to synthesize thiazolidinone derivatives using a rapid, safe and solvent-free grinding assisted approach. The newly synthesized compounds have been targeted due to their bioactivity in wide pharmaceutical uses, especially, as anti-proliferative agents. Two thiazolidinone derivatives having a diverse set of crucial functional groups were diagnosed with melting point (m.p), FT-IR

A series of 4-(substituted benzylidene-amino)-1,5-dimethyl-2-phenyl-1,2-dihydropyrazol-3-ones (1-17) was synthesized and tested in vitro for its antimicrobial and anticancer potentials. The biological screening results indicated that compounds having m-chloro substituent on benzaldehyde portion showed antimicrobial potential, whereas compounds having chloro, methoxy, and hydroxyl groups showed anticancer potential. The quantitative structure activity relationship (QSAR) studies indicated the importance of topological parameter, valence first order molecular connectivity index in describing antifungal activity. The developed QSAR models, however, were statistically insignificant with reference to anticancer activity of the synthesized compounds.
Design, crystal structures and sustainable synthesis of family of antipyrine derivatives: Abolish to bacterial and parasitic infection
This work explores the facile synthesis of a series of antipyrine acetylinic framework (3a-3h). The newly synthesized compounds are recognized by IR, NMR (H-1, C-13), X-ray diffraction. This collection played indispensable role in the development of biologically active agents. Our goal is to enable adoption of green chemistry within the pharmaceutical industry for the benefit of society, industry and the environment. This work articulates a new possible scaffold for drug discovery against protozoal pathogens (Entamoeba histolytica and Giardia lamblia) and bacterial strain (Staphylococcus aureus, Vibrio cholera, E. coli, Bacillus subtillus). The purpose of the present undertaking is to put low price anti parasitic drug using green technology. It is envisaged that the alliance of anti pyrine derivative and acetylene framework into a single scaffold boosts the effectiveness of anti bacterial as well as anti-parasitic treatment and may be vital for meeting future challenges in medicinal world.
