About TTI-0102

Thiogenesis' lead compound, TTI-0102, is an asymmetric disulfide that acts as a precursor to the thiol-active compound cysteamine; it also has additional therapeutic properties that may provide therapeutic advantages over cysteamine. Importantly, TTI-0102 is a new chemical entity ("NCE") with an initial US patent granted in November 2021 and additional US and international patents pending. Thiols are versatile bio-active molecules that are known to be involved in a several chemical reactions and metabolic processes making them exciting candidates for a number of therapeutic applications. TTI-0102 was developed to address the challenges of thiol-active drugs, including their short half-lives and adverse side effects.

Potential indications for TTI-0102 as a therapeutic, based on its versatile chemistry as a thiol-active compound:
