Comparative phytochemical and biological assessment of (pomegranate) peel extracts at different growth stages in the Taif region, Saudi Arabia.

The medicinal and commercial value of pomegranate peel is attributed to its rich content of phenolic compounds, yet little is known about their concentrations and biological activity across different ripening stages. Pomegranate peels at different growth stages 1-3 (40, 80, and 120 days after fruit appearance respectively) were collected, dried, and macerated with 90% methanol. Stage 2 and stage 3 extract showed significant antimicrobial activity against , and .

Evaluation of binding and inhibition mechanism of dietary phytochemicals with sphingosine kinase 1: Towards targeted anticancer therapy.

Sphingosine kinase 1 (SphK1) has recently gained attention as a potential drug target for its association with cancer and other inflammatory diseases. Here, we have investigated the binding affinity of dietary phytochemicals viz., ursolic acid, capsaicin, DL-α tocopherol acetate, quercetin, vanillin, citral, limonin and simvastatin with the SphK1.

Evaluation of pyrazolopyrimidine derivatives as microtubule affinity regulating kinase 4 inhibitors: Towards therapeutic management of Alzheimer's disease.

Microtubule affinity regulating kinase 4 (MARK4) plays essential role in the tau-assisted regulation of microtubule dynamics. Over expression of MARK4 causes early phosphorylation of Ser262 of tau protein which is essential for microtubule binding. Hyperphosphorylation of tau protein causes the formation of paired helical fragments and neurofibrillary tangles, the hallmarks of Alzheimer's disease.
