Abstract:
A novel library of 1,2,4-oxadiazole bearing isoxazole-pyrazole derivatives (13a-j) were designed, synthesized and evaluated for their anticancer activity towards MCF-7 (breast cancer), A549 (lung cancer), DU-145 (prostate cancer) and MDA MB-231 (breast cancer) human cancer cell lines by MTT assay. Here etoposide used as standard drug. Among them, five compounds (13b, 13c, 13d, 13h and 13i) were exhibited more potent activity. In which compound 13h was the most promising compound against all cell lines MCF-7, A549, DU-145 and MDA MB-231.

Abstract:
Abstract We studied the electric quadrupole interactions of Oxygen isotopes in a TiO2 single crystal. For 13O and 19O nuclei, quadrupole coupling constants were measured by the β-NMR technique, and for the 17O nucleus the FT-NMR technique was utilized. We synthesized a TiO2 single crystal which was enriched in 17O up to 5 atom % to observe NMR signals without any perturbations from impurities. Using the known quadrupole moment of 17O, EFGs at an O site in TiO2 and the quadrupole moments of 13O and 19O were determined.

Abstract:
Pyrazolo[1,5-a]pyrimidines 5a–c, 9a–c and 13a–i were synthesized for evaluation of their in vitro antimicrobial properties against some microorganisms and their immunomodulatory activity. The biological activities of pyrazolo[1,5-a]pyrimidines showed that the pyrazolo[1,5-a]pyrimidines (5c, 9a, 9c, 13a, 13c, 13d, 13e and 13h) displayed promising antimicrobial and immunomodulatory activities. Studying the in silico predicted physicochemical, pharmacokinetic, ADMET and drug-likeness properties for the pyrazolo[1,5-a]pyrimidines 5a–c, 9a–c and 13a–i confirmed that most of the compounds (i) were w

Abstract:
Introduction: Cancer is still an untreatable disease and the second leading cause of death globally. The heterocyclic compounds have always played a major role in the anticancer drug discovery program. 1,2,4-Triazine-6-ones is a heterocyclic privileged structure with diversified activities. In the presented study, 21 novel 2,5-disubstituted-3-phenyl-1,2-dihydro-1,2,4-triazin-6 (5H)-one derivatives (13(a-k), 18(a-j) and 21(a1-a4, b)) have been synthesized and tested for their anticancer activity. Methods: The 2,5-disubstituted-3-phenyl-1,2-dihydro-1,2,4-triazin-6(5H)-one derivatives (13(a-k), 1
