Tryparsamide is an arsenic compound with activity against Spirochaetes bacteria. Tryparsamide is used in the treatment of syphilis and African sleeping sickness. For decades Tryparsamide remained the standard treatment for trypanosomiasis. Tryparsamide has two remarkable properties: first, it increases the resistance of the individual by improving his general physical status; and, second, the high penetrability for nervous tissue which it possesses may increase the potential spirocheticidal action of the drug.

S-(+)-niguldipine is a more active enantiomer and is a selective antagonist for the and α1A-adrenoceptor. In addition, it can be used for discriminating of alpha 1A- from alpha 1B-adrenoceptors. There were made attempts to investigate the antidepressant action of S-(+)-niguldipine on rats, but that studies were unsuccessful.

4,4’-Diamino-2,2’-stilbenedisulfonic acid (also known as amsonic acid) is used in the synthesis of dyes and optical brighteners or fluorescent whitening agents. Amsonic acid possesses estrogenic activity, and thus provided a possible mechanistic explanation for the complaints of impotency in factory workers exposed to this compound. In the 2-year feed studies on rodents, there was no evidence of carcinogenic activity of amsonic acid, in male or female F344/N rats receiving 12,500 or 25,000 ppm. In addition, there was no evidence of carcinogenic activity of this compound in male or female B6C3F1 mice receiving 6,250 or 12,500 ppm.

Nicofibrate is an antilipidemic drug. Treatment of diabetics led to a significant reduction in plasma cholesterol and triglycerides and brought the lipoprotein picture back within the norm. Nicofibrate did not lead to significant increases in uricaemia nor to any worsening in carbohydrate tolerance. Nicofibrate may also lead to a significant drop in plasma prothrombinic activity.

N-Gene Research Laboratories is developing BGP-15 (NP-51), a small molecule, orally available, indirect Jun kinase (JNK) inhibitor and insulin sensitiser, for glycaemic control in patients with type-2 diabetes mellitus, and as an adjunct treatment for insulin resistance due to antipsychotics or obesity. In March 2002, N-Gene Research Laboratories granted Allos Therapeutics an exclusive license to its intellectual property surrounding BGP 15 in the US. BGP-15 has previously been used in clinical trials for the treatment of skeletal muscle pathology associated with Type 2 Diabetes (through insulin sensitization), Duchenne Muscular Dystrophy (DMD) and heart failure (through anti-inflammatory and anti-fibrotic mechanisms). Via its action as a modulator of the cytoprotective response to cellularstress, and specifically as a poly (ADP-ribose) polymerase (PARP) inhibitor, heat shock protein-inducer, membrane lipid therapeutic and an antioxidant inducer, BGP-15 has previously been shown to protect against skeletal muscle dysfunction, damage and wasting.

Prazitone (also known as AGN-511) is a barbiturate derivative patented by Aspro-Nicholas Ltd. as a non-sedating anxiolytic and antidepressant

Bromebric Acid (Cytembena) is a derivative of bromoacrylic acid with cytostatic and antineoplastic activity. Chemical structure of Bromebric Acid is not related to any previous antineoplastic agent. In animal tumor screens, Jelinek and Semonsky noted antineoplastic activity of Cytembena against sarcoma 180, atlenocarcinoina of the lactic gland in mice, Ehrlich’s ascitic carcinoma, Yoshida’s ascitic sarcoma, and Zojdeln’s heap

Monophosphothiamine is thiamine derivative used for the treatment of neuritis, polyneuritis, asthenic conditions (weakness), as an additional remedy for chronic blood circulation insufficiency, chronic gastritis accompanied by motor and secretory disorders functions of the stomach. Monophosphothiamine underwent metabolic phosphorylation to active metabolite thiamine pyrophosphate, that acts as a coenzyme in the different metabolic process.
