Cysteine peptide is a tyrosinase inhibitor with skin-whitening, antioxidant and multi-regulatory activities. Cysteine peptide inhibits enzyme activity and blocks melanin transport, effectively reducing UV-B-induced skin erythema and pigmentation. Cysteine peptide synergistically maintains skin health by quenching ROS, resisting oxidative stress and promoting pheomelanin production. Cysteine peptide safely prevents daily ultraviolet damage and supports moderate sun exposure for vitamin D synthesis. Cysteine peptide also acts as a plant signaling factor to regulate vegetative growth, development and stress resistance responses .

Synonyms: Nickel monoxide
Nickel(II) oxide (nickel monoxide) is a chemical warfare agent that can enter the body through the respiratory tract and other routes, distributing to organs such as the lungs and testes. The nanoparticle form of nickel(II) oxide (NiO NPs) exhibits antibacterial, anti-leishmanial, anti-diabetic, and anti-cancer activities. NiO NPs can be activated by ultraviolet and visible light, generating reactive oxygen species (ROS). Nickel(II) oxide induces oxidative stress by generating reactive oxygen species, activating the TGF-β1-mediated MAPK and PI3K/AKT pathways, disrupting the MMPs/TIMPs balance, and upregulating the expression of inflammatory factors (IL-1β, IL-6) and apoptosis-related molecules (Bax, caspase-3, p53), while inhibiting the activity of the anti-apoptotic molecule Bcl-2. Nickel(II) oxide induces cytotoxicity, promotes fibrosis, triggers inflammatory responses, and causes apoptosis. Nickel(II) oxide can be applied in research on the safety assessment of nanomaterials, such as in the context of pulmonary fibrosis and reproductive system toxicity .

trans-Caffeic acid (Standard) is the analytical standard of trans-Caffeic acid (HY-121231). This product is intended for research and analytical applications. trans-Caffeic acid is a hydroxycinnamic acid widely distributed in coffee, propolis, and Lamiaceae herbs. trans-Caffeic acid exhibits significant antioxidant and photoprotective activities, and can be used in cancer-related research. trans-Caffeic acid readily undergoes reversible isomerization to form its cis-isomer in protic solvents, under high temperature, ultraviolet radiation, and stress conditions. Binding of trans-Caffeic acid with aluminum, lead, or copper ions attenuates isomerization and inhibits the formation of vinylcatechol, while complexation with lead or copper ions also promotes the formation of aesculetin .
