This study developed potentiometric sensors for detecting lurasidone HCl (LSH), a vital drug for treating schizophrenia and bipolar I disorder, in pharmaceutical formulations and biological samples. The sensors are based on screen-printed electrodes (SPE) modified with a molecularly imprinted polymer (MIP) synthesized using lurasidone as a template, 1-vinyl-2-pyrrolidine (VP) as a functional monomer, ethylene glycol dimethacrylate (EGDMA) as a crosslinker, and benzoyl peroxide as an initiator. The SPE was further modified with a conductive polyaniline (PANI) film and a polyvinyl chloride (PVC) layer containing MIP as an ionophore and multiwalled carbon nanotubes (MWCNT) as a transducing material along with 2-nitrophenyl octyl ether (2-NPOE) as plasticizer.

The discovery of novel CDK2 inhibitors is crucial for developing targeted anticancer therapies. Thus, in this study, we aimed to design, synthesize, and evaluate a series of novel pyrazole derivatives (2a-g, 7a-d, 8a and b, 9, and 10) for their potential as CDK2/cyclin A2 enzyme inhibitors. The newly synthesized compounds were screened at 50 μM for CDK2 inhibition, followed by IC profiling of the most promising candidates.
