(+)-K 252a

Descrizione:

(+)-K 252a è un prodotto naturale derivato dalla fermentazione del batterio Streptomyces, noto per le sue potenti attività biologiche. È classificato come un inibitore della chinasi proteica, mirato specificamente a varie chinasi coinvolte nelle vie di segnalazione cellulare. Questo composto presenta una struttura complessa caratterizzata da un nucleo tetraciclico, che contribuisce alla sua capacità di modulare processi cellulari come crescita, differenziazione e apoptosi. (+)-K 252a ha mostrato promesse in varie applicazioni farmacologiche, inclusi effetti neuroprotettivi e potenziali proprietà antitumorali. Il suo meccanismo d'azione implica l'inibizione di chinasi specifiche, il che può portare a modifiche nelle cascades di segnalazione cellulare. Inoltre, è stato studiato per i suoi effetti sul rilascio di neurotrasmettitori e sulla sopravvivenza neuronale. A causa della sua importanza biologica, (+)-K 252a funge da strumento prezioso nella ricerca biochimica e ha potenziali implicazioni terapeutiche, sebbene siano necessari ulteriori studi per comprendere appieno la sua efficacia e sicurezza in contesti clinici.

K-252A

CAS: 99533-80-9

K-252A is an antimicrobial agent that inhibits the growth of bacteria. It binds to the response element in the promoter region of genes and blocks gene transcription, thereby preventing protein synthesis. K-252A has been shown to inhibit the growth of bacteria that are resistant to many other antibiotics, including ampicillin, chloramphenicol, clindamycin, erythromycin, gentamicin and kanamycin. This drug also induces significant up-regulation of cyclic nucleotide phosphodiesterases (PDE) and cytosolic Ca2+ in vitro. K-252A has been shown to cause neuronal death in vitro by inhibiting axonal growth. K-252A also inhibits leukemia inhibitory factor (LIF) from binding to its receptor on mouse lymphocytes.
