A variety of zwitterionic adducts were synthesized by using means green chemistry method. The products contain the biologically active barbituric acid moiety embedded in zwitterion products. Both features are pharmaceutically relevant. The chemical structures were deduced by (1)H-, (13)C-, NMR and HRMS spectral analysis, and X-ray diffraction techniques. In(More)
Twenty-five benzophenone semicarbazones and thiosemicarbazones 3–27 were synthesized starting from benzophenones via hydrazones treated with different aryl isocyanates and isothiocyantes under reflux. All synthetic derivatives were evaluated for their urease inhibitory potential. Good to moderate inhibition trend against urease was observed with the IC50(More)
Lost myelin can be replaced after injury or during demyelinating diseases in a regenerative process called remyelination. In the central nervous system (CNS), the myelin sheaths, which protect axons and allow the fast propagation of electrical impulses, are produced by oligodendrocytes. The abundance and widespread distribution of oligodendrocyte(More)
Discovery of new urease inhibitors is an important approach towards the treatment of diseases caused by ureolytic bacteria. Urease has an important role in several pathologies, such as urolithiasis, peptic and duodenal ulcers, etc. In this regard, urease inhibitory activity of heterocyclic synthetic compounds 1–14, belonging to different chemical classes(More)
Thymidine phosphorylase (TP) over expression plays an important role in several pathological conditions, such as rheumatoid arthritis, chronic inflammatory diseases, psoriasis, and tumor angiogenesis. In this regard, a series of twenty-five 2-arylquinazolin-4(3H)-one derivatives 1-25 were evaluated for thymidine phosphorylase inhibitory activity. Six(More)
Thymidine phosphorylase (TP) catalyzes the cleavage of thymidine into thymine and 2-deoxy-α-d-ribose-1-phosphate. Elevated activity of TP prevents apoptosis, and induces angiogenesis which ultimately leads to tumor growth and metastasis. Critical role of TP in cancer progression makes it a valid target in anti-cancer research. Discovery of small molecules(More)
