    Anticancer potential of new n-acetyl pyrazoline derivatives of 1,3 diaryl/hetroaryl propenoes: Synethesis and evaluation
    (Central University of Punjab, 2013) Alex, Jimi Martin; Kumar, Raj
    Pyrazoles, categorized as nitrogen-containing heterocycles, are well known for their interminable participation in the field of perpetual research and development of therapeutical active agents. As a consequence pyrazoles became an inevitable core of numerous drugs having diverse activities. The broad spectrum of activities portrayed by the pyrazoles instigated the researchers to modify the pyrazole ring as 4,5-dihydro-1H-pyrazoles commonly known as 2-pyrazolines. This modification played a determining role in defining the biological activities of several compounds. The presence of aromatic/heterocyclic substituents on the pyrazoline ring only served to accentuate these activities. Literature survey also revealed that substitution such as amide group, acetyl groupetc.at N1 of the pyrazoline also played a decisive role in deciding the biological activity. The vast information obtained from literature survey stimulated us to synthesize compounds having 2-pyrazoline as the core moiety of which either the C3 or C5 was substituted with heterocyclic ring in addition to acetyl moiety at the N1 of the pyrazoline. The compounds were assessed for their anticancer potential against four cancer cell- MCF-7, H-460, T-47 D and A-549. MTT assay was carried out for testing the cell viability. The assay results revealed that certain compounds showed anticancer potential because these agents inhibited the proliferation of breast cancer cell lines but not against lung cancer cell line. Compounds showing good activity against the cancer cell lines were also evaluated for their antioxidant property especially against reactive oxygen species
