OTS964 is a potent, orally active compound that operates as a highly selective inhibitor of TOPK with an IC 50 of 28 nM [1]. Additionally, it demonstrates significant inhibitory action against cyclin-dependent kinase CDK11, specifically binding to CDK11B with a K d of 40 nM [2].
Cephradine sodium is the salt form of Cephradine (free base), a semi-synthetic cephalosporin antibiotic. Cefradin inhibits the last stage of bacterial cell wall synthesis by binding to certain penicillin-binding proteins which results in cell lysis. Cell lysis is mediated by bacterial cell wall autolytic enzymes. Cefradin may interfere with autolysin inhibitors.
