Tromantadine hydrochloride is a synthetic antiviral compound, which is a derivative of adamantane. It originates from chemical synthesis, tailored specifically to target viral processes. Tromantadine hydrochloride primarily exerts its effects by inhibiting the penetration of virus particles into host cells and impeding the subsequent stages of viral replication. This mode of action effectively reduces the viral load and hinders the progression of the infection. The primary use of Tromantadine hydrochloride lies in its application against herpes simplex viruses. It is utilized in topical formulations for the treatment of conditions such as cold sores and genital herpes. By limiting the ability of the virus to replicate and spread, Tromantadine hydrochloride assists in reducing the severity and duration of outbreaks. Research continues on its efficacy and potential applications, offering insights into broader antiviral treatments and prophylactic measures in virology.

Saquinavir is a HIV protease inhibitor drug that is used with other antiretroviral drugs for the treatment of HIV-1. As this drug prevents HIV protease activity, it prevents the proteolysis of the Gag polyprotein and thus results in non-infectious virus particles. Saquinavir mesylate is part of our Bio-X ™ Range. These products are aimed at life science researchers who need high quality ready-to-use products for assay development, screening or other R&D work. With a solubility datasheet and convenient vials, all of our Bio-X ™ products are in stock across our global warehouses for rapid delivery and ease of use.
