Breast cancer remains the leading cause of cancer-associated mortality in women. Research investigating novel therapeutic approaches is thus crucial, including phytotherapeutics. Pterostilbene (PTS) is a phytochemical agent with promising efficacy against breast cancer.

Diabetes mellitus is associated with an increased risk of cardiac complications; this study aimed to investigate effect of sitagliptin (SITA) alone or combined with -irradiation on diabetes-associated cardiac injury. Rats were treated with SITA (100 mg/kg per day; p.o.

The present study is concerned with the genetic discrimination of fifteen alfalfa cultivars from three different countries (Egypt, Australia, and USA) using two molecular approaches: inter-retrotransposon-amplified polymorphism (IRAP) markers and two chloroplast DNA barcodes K and the H in addition to the analysis of fifteen morpho-agronomic traits.

The reaction is mediated by the phosphonite PPh(catechyl) and proceeds via regioselective cycloaddition with an in situ-generated phospha-münchnone 1,3-dipole. This provides an efficient route to construct both highly substituted and polycyclic imidazoles directly from available substrates, without metal catalysts, and with access to product diversity.

This reaction proceeds via phosphorus-containing 1,3-dipoles, which undergo cycloaddition with alkenes with high stereo- and regioselectivity. The modularity of this reaction can be used to assemble a range of polysubstituted pyrrolines in one pot transformations.

The dihydropyridine 2 reaction products can be converted to synthetically useful piperidines. Application of the methodology to the preparation of enantioenriched quaternary chiral centers is also discussed.
