FGIN 1-27 (Standard)

FGIN 1-27 (Standard) is the analytical standard of FGIN 1-27 (HY-101059). This product is intended for research and analytical applications. FGIN-1-27 is a blood-brain barrier-penetrant TSPO ligand with a K_i value of 5 nM. FGIN 1-27 inhibits PKC-β, PKA/CREB, p38/ERK MAPK, MITF, tyrosinase, TRP-1, and TRP-2, thereby inhibiting melanogenesis and pigmentation. FGIN-1-27 alleviates X-ray radiation-induced astrocyte mitochondrial hyperfunction, reduces ROS and superoxide production, inhibits excessive activation of A1-type astrocytes, downregulates GFAP and C3 protein expression, and restores astrocyte proliferative capacity. FGIN-1-27 produces anticonvulsant effects in normal mice; in diazepam-withdrawn mice, the brain MDR pathway becomes subsensitive, and the anticonvulsant activity disappears. FGIN-1-27 attenuates pigmentation in zebrafish embryos and ameliorates UVB-induced skin pigmentation in guinea pigs. FGIN-1-27 directly stimulates testicular Leydig cells while upregulating luteinizing hormone levels, causing an acute increase in serum testosterone in male rats. FGIN 1-27 can be used for research related to hyperpigmentation, epilepsy, brain injury, and other diseases.
