Naxaprostene (CG 4305) is a prostacyclin analogue, which causes concentration dependent inhibition of thrombocyte function. Naxaprostene is more selective for IP receptors and tends towards partial agonism. Naxaprostene prevented thrombotic arterial occlusion in rabbits.

Deprostil is prostaglandin E analog. The drug exhibits a prolonged inhibition of basal gastric acid secretion. Deprostil is the orally active anti-ulcer agent. It is a racemate with four possible optical isomers. Like deprostil the (nat)- and (epi)-isomers appear to be potentially useful therapeutic agents for the treatment of hypergastrlc acid secretion and peptic ulcers.

Dicirenone is an aldosterone antagonist. It is used as a hypotensive agent. Dicirenone inhibited the effects of aldosterone on urinary K(+):Na(+) ratios and the binding of [(3)H]aldosterone to renal cytoplasmic and nuclear receptors. Dicirenone blocked the action of aldosterone on Na-K ATPase. Cytoplasmic binding of [(3)H]aldosterone and dicirenone was similar in magnitude and involved the same set of sites. It had no effect on adrenal steroidogenesis.

Iotranic Acid is triiodobenzoic acid derivative with potential application as new cholangiographic contrast media for liver imaging

Ioxotrizoic acid is acylated 3,5-diaminopolyhalobenzoic acid derivative patented by Sterling Drug Inc. as X-ray contrast agent for liver and spleen.

Feloprentan is an endothelin receptor antagonist.

Butilfenin is N-substituted iminodiacetic acid derivative that was studied as tridentate ligand to form a technetium-99m complex.

Metheptazine was studied as an analgesic agent.

Norleucine (L-norleucine) is a 2-aminohexanoic acid is an alpha-amino acid that is caproic acid substituted by an amino group at position 2. It derives from a hexanoic acid. It is used experimentally to study protein structure and function. Norleucine appears to inhibit bacterial growth due to incorporation into proteins in place of methionine, as the analogue inhibits methionine incorporation but does not significantly reduce its synthesis. L-norleucine had antiviral activity in thermophile. In vitro and in vivo assays revealed that L-norleucine significantly suppressed metastasis of gastric and breast cancer cells. L-norleucine interacted with hnRNPA2/B1 protein to inhibit the expressions of Twist1 and Snail, two inhibitors of E-cadherin, and promote the E-cadherin expression, leading to the inhibition of tumor metastasis.

Cefuracetime is an impurity of Cefuroxime, which is an antibacterial agent.
