  3. Trpvicin

Trpvicin 是一种强效且亚型选择性的 TRPV3 抑制剂,其对 hTRPV3-WT 和 hTRPV3-G573S 突变体的 IC50 值分别为 0.41 μM 和 0.22 μM。Trpvicin 对其他 TRP 家族成员 (例如 TRPV1/2/4/5/6、TRPA1 和 TRPM8) 仅表现出微弱抑制作用。Trpvicin 通过结合 VSLD-PD 位点稳定通道关闭状态,从而抑制 TRPV3 通道。Trpvicin 在 G573S 突变体中,可进入中央空腔通过对称性重构和孔道阻塞增强抑制效果。Trpvicin 在小鼠模型中可抑制瘙痒和脱发。Trpvicin 可用于炎症和免疫学相关研究。

生物活性

Trpvicin is a potent and subtype-selective TRPV3 inhibitor with IC50s of 0.41 and 0.22 μM for hTRPV3-WT and hTRPV3-G573S mutant, respectively. Trpvicin exhibits minimal effects on other TRP family members (such as TRPV1/2/4/5/6, TRPA1 and TRPM8). Trpvicin inhibits the TRPV3 channel by stabilizing it in a closed state via VSLD-PD binding. Trpvicin accesses additional binding sites inside the central cavity of the G573S mutant to remodel symmetry and block the channel. Trpvicin inhibits itch and hair loss in mouse models. Trpvicin can be used for study of inflammation and immunology[1].

体外研究
(In Vitro)

Trpvicin (0-100 μM) 剂量依赖性地抑制 HEK293T 细胞中表达的 TRPV3-WT 和 hTRPV3-G573S 通道电流,在 10 μM 浓度下达到几乎完全抑制,其效力与 Ruthenium Red (HY-103311) 相当[1]
Trpvicin (10 μM,24 小时) 可挽救表达细胞毒性 hTRPV3-G573S 突变体的 HEK293T细胞活力,表明其对组成型活性通道具有功能性阻断作用[1]
。 Trpvicin (0-100 μM) 剂量依赖性地抑制 HEK293T 细胞中异源表达的 hTRPV3-G568V 和 mTRPV3-G568V 通道电流[1]
Trpvicin 可有效抑制 HEK293T 细胞中异源表达的野生型小鼠 TRPV3 (mTRPV3-WT) 和功能获得型突变体mTRPV3-G568V,IC50 值分别为 0.38 μM 和 0.42 μM[1]
Trpvicin 对 hTRPV3 A556V、A560T 和 F601A 突变体的效力与野生型通道相比显著降低 (分别降低了 158 倍、162 倍和 208 倍),这表明这些残基是 Trpvicin 结合的关键决定因素[1]
Trpvicin 对 hTRPV3-G573S-F666A、hTRPV3-G573S-F666Y 和 hTRPV3-G573S-T665A 双突变体的效力分别降低了 17 倍、12 倍和 16 倍,表明这些残基在中央空腔区域具有重要的药物结合功能,其作用超越其首要的 VSLD-PD 结合位点[1]

Trpvicin (10 和 100 µM,皮内注射,于 SLIGRL 注射前 30 分钟给药) 能显著减少由 SLIGRL (HY-P1308) 诱发的小鼠急性搔抓行为[1]
Trpvicin (30 和 100 mg/kg,口服灌胃,自 MC903 造模前 5 天开始,每日给药持续 12 天) 可缓解 MC903 (HY-10001) 诱导的小鼠皮炎模型中的慢性搔抓和耳部肿胀[1]
Trpvicin (1 wt%,局部涂抹,自出生后第 50 天起每日给药 16 天) 能有效改善雌性和雄性 Trpv3+/G568V 基因敲入小鼠的脱发情况[1]

Animal Model: Adult wild-type male C57BL/6J mice (8-12 weeks old) topically treated with 20 μL of 100 μM MC903 on both ears, daily for 7 days[1]
Dosage: 30 and 100 mg/kg
Administration: p.o., daily starting from 5 days before MC903 for 12 days
Result: Reduced the scratching behavior at a dose of 100 mg/kg, compared to the vehicle-treated control mice in the MC903-induced chronic itch model.

Dosage: 1 wt%
Administration: topically, daily from postnatal day 50 (P50) for 16 days
Result: Showed substantially longer hair shafts and less hair shedding throughout the period.
Demonstrated efficacy in rescuing hair loss in both male and female mouse models.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
