Uncoupled cell cycle without mitosis induced by a protein kinase inhibitor, K-252a
The staurosporine analogues, K-252a and RK-286C, were found to cause DNA re-replication in rat diploid fibroblasts (3Y1) without an intervening mitosis, producing tetraploid cells. Analysis of cells synchronized in early S phase in the presence of K-252a revealed that initiation of the second S phase required a lag period of 8 h after completion of the previous S phase. Reinitiation of DNA synt...
متن کاملThe effect of K-252a, a potent microbial inhibitor of protein kinase, on activated cyclic nucleotide phosphodiesterase.
K-252a, an indole carbazol compound of microbial origin, inhibited activation of bovine brain phosphodiesterase induced by calmodulin (CaM), sodium oleate, or limited proteolysis with almost equal potency. Kinetic analysis revealed that the CaM-activated phosphodiesterase (CaM-PDE) was competitively inhibited by K-252a with respect to CaM. On the other hand, inhibition of the trypsin-activated ...
متن کاملDifferential effects of the protein kinase inhibitor K-252a on the in vitro survival of chick embryonic neurons.
The effects of the protein kinase inhibitor K-252a on the in vitro survival of different populations of chick embryonic neurons were tested. Following dissociation from the corresponding ganglia by trituration, the neurons were cultured on laminin-coated dishes in both the presence and absence of their respective neurotrophic factor. K-252a alone promoted long-term neuronal survival of dorsal r...
متن کاملSFHS: Reusable catalyst for the synthesis of polyhydroquinoline derivatives and its molecular docking studies against tyrosine protein kinase
An efficient synthesis of polyhydroquinoline derivatives is achieved via Hantzsch condensation reaction between aldehydes, dimedone, ethyl acetoacetate and ammonium acetate in the presence of catalytic amount of SFHS in ethanol. This method gives remarkable advantages such as shorter reaction time, simple workup procedure and good to excellent yields. Furthermore the catalyst can be recovered c...
