Fyn
Fyn is a Src family tyrosine kinase represented in brain by the neuronal isoform p59FynB, where Src and Fyn constitute the two main tyrosine kinases involved in neuronal growth and myelination[1]. Mechanistically, Fyn participates in Src-family signaling modules that regulate inflammation, apoptosis, neuroinflammation, and epileptogenesis in experimental systems[2][3]. In pulmonary endothelial inflammation models, fyn knockdown increased caspase-3 activity, reduced viable cell numbers, and intensified LPS-induced lung injury in fyn−/− mice, identifying Fyn as a negative regulator of inflammation-induced apoptosis[2]. In temporal lobe epilepsy models, the Fyn-PKCδ pathway linked status epilepticus to neuroinflammation and epileptogenesis, while saracatinib reduced seizures, gliosis, neurodegeneration, phosphorylated Fyn/Src-419, PKCδ-tyr311, nitrooxidative stress, and proinflammatory cytokines[3]. Compared with related isoforms, Fyn showed an opposite endothelial apoptosis phenotype to Yes, because yes knockdown lowered caspase-3 activity and increased viable cells under cytomix stimulation[2]. For experimental applications, saracatinib functions as a Src/Fyn tyrosine kinase inhibitor for probing epileptogenesis-associated neuroinflammatory and nitrooxidative pathways[3].

Antifibrotic agent 1
0 ImagesCat. No.: HY-176194Antifibrotic agent 1 is an orally active anti-idiopathic pulmonary fibrosis (IPF) agent. Antifibrotic agent 1 effectively attenuates IPF-related processes, including TGF-β induced EMT and FMT processes, as well as pro-fibrotic M2 polarization. Antifibrotic agent 1 selectively inhibits CSF-1R, PDGFR-α and Src family kinases (SFKs), while sparing VEGFRs, FGFRs and Abl to minimize off-target toxicity. Antifibrotic agent 1 has potent anti-fibrotic activity in Bleomycin (BLM) (HY-108345)-induced pulmonary fibrosis mice model.
