This work describes the antitrypanocidal activity of two hydroxamic acid derivatives containing o-ethoxy (HAD1) and p-ethoxy (HAD2) as substituent in the aromatic ring linked to the isoxazoline ring. HAD1 and HAD2 induced a significant reduction in the nu

Microtubule affinity-regulating kinase 4 (MARK4) is a serine/threonine kinase involved in the phosphorylation of MAP proteins that regulates microtubule dynamics and abets tumor progression by participating in oncogenic signaling pathways. It is overexpressed in multiple human malignancies and no drug is available for this potential therapeutic target at present. Therefore, using the structure based drug design strategy, a library of hydroxylamine derivatives of morpholine were designed and synthesized as small molecule inhibitors of MARK4. Compound 32 having the CF3 group at the ortho position of the phenyl ring tethered with the >CNOH core and the hinge binder morpholine component was found to be a potent and selective inhibitor of MARK4 over thirty other serine-threonine kinases. Study of cell viability and compound induced morphological changes in MCF-7 cancer cells discovered that molecule 32 caused death of cancerous cells through the mechanism of apoptosis. Compound 32 may be transported and delivered to the target site through the blood stream, and has promising antioxidant potential. Such bio-active molecules could serve as optimized lead candidates in drug discovery for cancer treatment through MARK4 inhibition.

Antibiotic resistance among clinically significant bacterial pathogens, such as methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant S. aureus (VRSA) is becoming a prevalent threat to public health, and new antibacterial agents with novel mechanisms of action hence are in an urgent need. As a part of continuing effort to develop antibacterial agents, we rationally designed and synthesized two series of 4,5-dihydroisoxazol-5-yl and 4,5-dihydroisoxazol-3-yl-containing benzamide derivatives that targeted the bacterial cell division protein FtsZ. Evaluation of their activity against a panel of Gram-positive and -negative pathogens revealed that compound A16 possessing the 4,5-dihydroisoxazol-5-yl group showed outstanding antibacterial activity (MIC, ≤0.125–0.5 μg/mL) against various testing strains, including methicillin-resistant, penicillin-resistant and clinical isolated S. aureus strains. Besides, further mouse infection model revealed that A16 could be effective in vivo and non-toxic to Hela cells. Finally, a detailed discussion of structure-activity relationships was conducted, referring to the docking results. It is worth noting that substituting a 4,5-dihydroisoxazole ring for the isoxazole ring not only broadened the antibacterial spectrum but also resulted in a significant increase in antibacterial activity against S. aureus strains. Taken together, these results suggest a promising chemotype for the development of new FtsZ-targeting bactericidal agents.
