Inhibits in vitro phosphorylation of c-Kit. Also inhibits SCF (stem cell factor)-induced c-kit phosphorylation in 501mel human melanoma cells | [Biological Activity]
isck03 is an inhibitor of scf-mediated c-kit activation.the signaling downstream of scf/c-kit plays a key role in the development of various mammalian cells, such as mast cells, melanocytes, primordial germ cells, and hematopoietic progenitor cells. | [in vitro]
previous study showed that the pretreatment of 501mel cells with isck03 could dose-dependently inhibit scf-induced c-kit phosphorylation. isck03 could also inhibit the phosphorylation of p44/42 erk mitogen-activated protein kinase that was known to be involved in scf/c-kit downstream signaling. however, isck03 was not able to inhibit hepatocyte growth factor-induced phosphorylation of p44/42 erk proteins [1]. | [in vivo]
to determine the in vivo efficacy, isck03was orally administered to depilated c57bl/6 mice. results showed that the oral administration of isck03 could induce the dose-dependent depigmentation of newly regrown hair, and this was reversed with cessation of isck03 treatment. in addition, the topical application of isck03 could promote the depigmentation of uv-induced hyperpigmented spots on n brownish guinea pig skin. moreover, the fontana–masson staining analyses showed epidermal melanin was diminished in spots treated with isck03 [1]. | [References]
