In search of novel antidiabetic agents, we synthesized a new series of chalcones with benzimidazole scaffolds by an efficient 'one-pot' nitro reductive cyclization method and evaluated their α-glucosidase and α-amylase inhibition studies. The 'one-pot' nitro reductive cyclization method offered a simple route for the preparation of benzimidazoles with excellent yield and higher purity compared to the other conventional acid- or base-catalyzed cyclization methods. H, C NMR, IR, and mass spectrum data were used to characterize the compounds.

Background: Sulfonamides are widely used carbonic anhydrase inhibitors (CAIs) in clinical settings, however, their nonspecific inhibition of multiple carbonic anhydrase isoforms can lead to reduced efficacy and side effects. This study aimed to develop sulfanilamide-diazo derivatives incorporating benzoic acid moieties as novel inhibitors of hCA II activity to reduce side effects and enhance selectivity for different CA isozymes.

Methods: We investigated the interaction between these derivatives and the hCA II isozyme via various spectroscopic and docking methods.

Systems composed of several multi-layer compounds have been extremely useful in tailoring different quantum physical properties of nanomaterials. This is very much true when it comes to semiconductor materials and, in particular, to heterostructures and heterojunctions. The formalism of a position-dependent effective mass has proved to be a very efficient tool in those cases where quantum wells emerge either in one or two dimensions.

Introduction: Type II Diabetes mellitus (T2DM) patients often do not achieve glycemic control with oral hypoglycemic agents (OHAs). There are two main approaches to address this challenge: transitioning to a triple OHA regimen, or adding Insulin to the existing dual OHA regimen.

Aim: This study aimed to compare the efficacy of adding Insulin to dual OHAs (Sitagliptin + Metformin) against adding a third OHA to Sitagliptin + Metformin in achieving glycemic control among patients with uncontrolled T2DM.
