Microphthalmia Associated Transcription Factor (MITF) Inhibitor

ML329 is a micropthalmia-associated transcription factor (MITF) inhibitor, which inhibits TRPM-1 promoter activity with an IC₅₀ of 1.2 μM.

TT-012 is a MITF inhibitor with a human MITF IC₅₀ of 13.1 nM and a human MITF K_d value of 15.5 nM. TT-012 reduces mRNA levels of MITF downstream genes linked to melanosome biogenesis, cell survival, and proliferation, and upregulates cell cycle-inhibiting genes. TT-012 can be used for the research of melanoma^[1][2][3].

PDRN (Polydeoxyribonucleotide) is a deoxynucleotide polymer mainly derived from the sperm of rainbow trout or salmon. PDRN inhibits pro-inflammatory factors and promotes VEGF expression via the cAMP-PKA pathway by activating the adenosine A_2A receptor (A_2AR), thereby driving angiogenesis and collagen deposition in fibroblasts. Degradation products of PDRN provide DNA raw materials for proliferating cells through the salvage synthesis pathway, accelerating re-epithelialization. PDRN reduces melanin synthesis and cell apoptosis by upregulating ERK/AKT phosphorylation and inhibiting the activities of MITF and tyrosinase, and resists skin aging by attenuating nuclear autophagy and blocking the interaction between LC3-SIRT1. PDRN is mainly used for wound repair, post-aesthetic surgery recovery and anti-aging research.

10 (E)-Pentadecenoic acid (trans-10-Pentadecenoic acid) is a melanin synthesis inhibitor. 10 (E)-Pentadecenoic acid inhibits nuclear translocation and reduces the protein level of phosphorylated microphthalmia-associated transcription factor (MITF), as well as decreases intracellular tyrosinase activity. 10 (E)-Pentadecenoic acid can be used in the research of skin pigmentation disorders.
