The present invention relates to compounds or pharmaceutically-acceptable salts thereof, processes for preparing them, pharmaceutical compositions containing them and their use in therapy. The invention particularly relates to compounds that are polo-like kinase (PLKs) inhibitors useful for the treatment of disease states mediated by PLK, especially PLK4, in particular such compounds that are useful in the treatment of pathological processes which involve an aberrant cellular proliferation, such as tumour growth, rheumatoid arthritis, restenosis and atherosclerosis.
Design, synthesis of novel (Z)-2-(3-(4-((3-benzyl-2,4-dioxothiazolidin-5-ylidene)methyl)-1-phenyl-1H-pyrazol-3-yl)phenoxy)-N-arylacetamide derivatives: Evaluation of cytotoxic activity and molecular docking studies

the screened derivatives demonstrated moderate to promising cytotoxicactivity. Some of the derivatives, particularly compound 11d and 11n have shown promising cytotoxicactivity with IC50 values 0.604 μM and 0.665 μM compared to standard drug cisplatin and compounds 11a, 11e and 11g also have shown considerable cytotoxicactivity and the rest of the derivatives have shown moderate activity.

N-4-piperazinyl derivatives of ciprofloxacin 2a-g were prepared and tested for their cytotoxic activity. The primary in vitro one dose anticancer assay experienced promising cytotoxic activity against different cancercell lines especially non-small celllungcancer. Independently, compounds 2b, 2d, 2f and 2g showed anticancer activity against human non-small celllungcancerA549cells (IC50=14.8, 24

easily and efficiently from inexpensive and commercially available substrates. We tested this class of alkaloids in the alkylation of glycine derivative, carried out under phase-transfercatalyst conditions. The presented hybrid catalysts offer both high reaction yields (up to 97%) and high enantioselectivities of the obtained product (up to 94% ee).

4-piperazinylquinolin-2(1H)-ones with variable aromatic moieties and Mannich bases as Sorafenib analogues as potential inhibitors of angiogenesis. In this study, we investigated the impact of replacing the linker aromaticring with cyclic tertiary amines and the effect of incorporation of variably substituted distal rings. We hypothesized that cyclic tertiary amines would improve pharmacokinetic properties
