Tiossulfato de sódio

Descrição:

Tiossulfato de sódio, com o número CAS 7772-98-7, é um composto inorgânico comumente representado pela fórmula Na2S2O3. Aparece como um sólido cristalino branco que é altamente solúvel em água, formando uma solução incolor. Tiossulfato de sódio é conhecido por suas propriedades redutoras e é frequentemente utilizado em várias aplicações, incluindo fotografia, tratamento de água e como antídoto para envenenamento por cianeto. Age convertendo o cianeto tóxico em um composto menos prejudicial. A substância também é utilizada em química analítica como um titulante em reações redox, particularmente em titulações iodométricas. Além de sua reatividade química, Tiossulfato de sódio é relativamente estável em condições normais, mas pode se decompor quando exposto a ácidos fortes ou calor, liberando dióxido de enxofre e outros produtos. Seu perfil de segurança indica que geralmente é considerado não tóxico, embora possa causar irritação na pele e nos olhos ao contato. No geral, Tiossulfato de sódio é um composto versátil com utilidade significativa tanto em ambientes industriais quanto laboratoriais.

Sodium thiosulfate is a salt that is used as an antimicrobial agent. It has been shown to inhibit the toll-like receptor 4 (TLR4) and TLR2, which are important in the innate immune response. It has also been shown to suppress inflammation and tumor formation in vitro and in vivo. Sodium thiosulfate has been shown to inhibit the growth of squamous carcinoma cells by inducing apoptosis. The anti-cancer effect of sodium thiosulfate is due to its ability to reduce oxidative stress and increase antioxidant activity in cancer cells. It also inhibits potassium dichromate induced cancer cell proliferation by reducing redox potential. This salt may be useful for treating malignant brain tumors, where it has been shown to inhibit glioma cell proliferation, induce apoptosis, and reduce metastasis via reduction of angiogenesis.
