Design, in silico studies and biological evaluation of novel chalcones tethered triazolo[3,4-a]isoquinoline as EGFR inhibitors targeting resistance in non-small cell lung cancer.

A novel series of six [1,2,4]triazolo[3,4-a]isoquinolin-3-yl)-3-(1,3-diphenyl-1H-pyrazol-4-yl)prop-2-en-1-ones (3a-3f) was designed and synthesized. They were characterized based on spectral and elemental analyses. In silico studies were also committed to provide insights and a better understanding of their structural features.

Cellular Therapy via Spermatogonial Stem Cells for Treating Impaired Spermatogenesis, Non-Obstructive Azoospermia.

Male infertility is a major health problem affecting about 8-12% of couples worldwide. Spermatogenesis starts in the early fetus and completes after puberty, passing through different stages. Male infertility can result from primary or congenital, acquired, or idiopathic causes.

Biological Activity, Apoptotic Induction and Cell Cycle Arrest of New Hydrazonoyl Halides Derivatives.

Background: The hydrazonoyl halides are presently an important target in the field of medicinal chemistry. The interest in the chemistry of hydrazonoyl halides is a consequence of the fact that they undergo a wide variety of reactions which provide routes to a myriad of both heterocyclic and acyclic compounds. In addition, they have diverse biological activities such as antiviral, anthelmintic, antiarthropodal, fungicidal, herbicidal, insecticidal, pesticidal, acaricidal and miticidal Activity correlated to the presence of hydrazonoyl halides.
