Discovery of the selective and nanomolar inhibitor of DPP-4 more potent than sitagliptin by structure-guided rational design.

Various therapeutic targets and approaches are commonly employed in the management of Type 2 Diabetes. These encompass diverse groups of drugs that target different mechanisms involved in glucose regulation. Inhibition of the DPP-4 enzyme has been proven an excellent target for antidiabetic drug design.

Pregnenolone derivatives for the treatment of Alzheimer's disease: synthesis, and inhibition of amyloid β peptide aggregation, acetylcholinesterase and carbonic anhydrase-II.

The amyloid state, which is a specific conformation of proteins, offers valuable information about both functional protein structures and the pathological assemblies associated with various diseases. One of the major hallmarks of Alzheimer's disease includes primarily the extracellular build-up of a peptide known as amyloid-β, which has a sequence consisting of 39 to 42 amino acid residues, and the formation of intracellular neurofibrillary tangles mostly consisting of hyperphosphorylated tau protein. Drugs that are expected to reduce Aβ production, prevent Aβ aggregation, and promote Aβ clearance are promising approaches for treating AD.

Antiproliferative Activity of Lignans from : Evidence Supported by Docking Studies.

Background: The aim of the current study was to investigate the anticancer potential of bioactive compounds isolated from the leaves of (). Lignans from were previously described to possess antibacterial, antileishmanial, and antioxidant properties. Nevertheless, the antiproliferative activity of cycloolivil (1), ferruginan (2), and ferruginan A (3) have not been investigated in depth.
