Fursultiamine, also known as thiamine tetrahydrofurfuryl disulfide (TTFD) is an oral FDA- approved thiamine derivative for treating vitamin B1 deficiency and is very rapidly metabolized into thiamine. Fursultiamine possesses a mild beneficial effect in patients with Alzheimer's disease. The improvement could be observed not only in their emotional or other mental symptoms but also in intellectual function. Only mildly impaired subjects showed cognitive improvement. In addition was shown, that fursultiamine have a beneficial clinical effect on some autistic children. Some relatively recent experiments have revealed that fursultiamine was a unique antagonist of hepcidin in vitro that could serve as a template for the development of drug candidates that inhibit the hepcidin-ferroportin interaction. This inhibition is a key for the treatment of anemia of inflammation (AI), a common in patients with infection, autoimmune diseases, cancer, and chronic kidney disease.

Cocarboxylase is the coenzyme form of Vitamin B1 present in many animal tissues. Thiamine pyrophosphate (cocarboxylase) is the active form of thiamine, and it serves as a cofactor for several enzymes involved primarily in carbohydrate catabolism. Pancreatic cells obtain thiamin from their surroundings and enzymatically convert it into thiamin pyrophosphate (TPP) in the cytoplasm; TPP is then taken up by mitochondria via a specific carrier the mitochondrial TPP transporter (MTPPT; product of the SLC25A19 gene).

Octotiamine is an analogue of vitamin B1. As a component of vitamin complex used for the treatment of vitamin B1 deficiency; vitamin B1 supplement.

Dicethiamine hydrochloride (DCET) is a vitamin B(1) derivative that has excellent absorbability and transformability in tissues. It is an analogue of thiamine, improved performance in an animal model of complex fatigue.

Thiamine disulfide is a vitamin B1 derivative. It is used as a component of vitamin complexes for the treatment of neurological and other disorders associated with disturbance of metabolic functions influenced by B-complex vitamins, including diabetic polyneuropathy, alcoholic peripheral neuritis and post-influenzal neuropathies, for the treatment of neuritis and neuralgia of the spinal nerves, especially facial paresis, cervical syndrome, low back pain, and ischialgia. It has being shown to be a potent inhibitor of human immunodeficiency virus (type-1) production, suggesting that thiamine disulfide may be important for AIDS chemotherapy.
