mu-Conotoxin Cn IIIC(CAS#936616-33-0)

Introduction

Ω-conotoxin is a natural polypeptide secreted by CONUS. It has the following properties: has a small molecular weight, highly stable, strong antioxidant properties, has a certain moisturizing effect and promote collagen synthesis and other characteristics.

Omega-conotoxin is mainly used in the cosmetic field of anti-wrinkle and skin care. It can reduce cell aging and the appearance of skin wrinkles by enhancing the resistance of skin cells, reducing cell oxidative damage, and inhibiting the production of free radicals. At the same time, Omega-conotoxin can also enhance skin elasticity, improve skin firmness, improve skin texture.

The method for preparing ω-conotoxin is generally to extract and separate the effective components from CONUS, and then synthesize them by protein engineering technology or prepare them by microbial fermentation.

Regarding the safety information of ω-conotoxin, no obvious side effects have been found. However, it is still necessary to follow the product guidelines and recommendations to avoid excessive use or long-term use. For individual people who may have allergies or sensitivities, it is recommended to perform a skin test before use. If there is an abnormal reaction, you should stop using it immediately.

Application
µ-Conotoxin CnIIIC is a 22‑amino‑acid conopeptide from Conus consors that acts as a highly potent, persistent blocker of voltage‑gated sodium channels (IC₅₀ = 1.3 nM for Nav1.4) and an antagonist of α3/β2 nicotinic acetylcholine receptors. In pharmaceutical research, it is an essential tool for studying nerve‑signal transmission, pain pathways, and muscle excitability, particularly through its Nav1.4 selectivity. Engineered derivatives have demonstrated enhanced stability and prolonged neuromuscular blockade with reduced toxicity, supporting next‑generation anesthetics and muscle relaxants. In neurocosmetics, the peptide is recognized as a novel ingredient that delivers an immediate anti‑wrinkle effect and facial‑tightening sensation by relaxing facial muscles without eliminating natural expression. Its high stability and precise mechanism make it a versatile building block for drug discovery and advanced skincare formulations, including serums, creams, and eye contour products.
