(+)-Fadrozole (FAD-286) is an aldosterone synthase inhibitor. The drug was tested in vivo in preclinical models of hypertension, heart failure and was shown to reduce retinal neovascularization in rats with oxygen-induced retinopathy.

Levonadifloxacin is the S-(-) isomer of the benzoquinolizine fluoroquinolone nadifloxacin and is two- to four-fold more active than the racemic mixture. Levonadifloxacin is a potent antibacterial agent against Gram-positive bacteria especially against methicillin resistance Staphylococcus aureus. It also possesses potent bactericidal activity against other resistant variants like quinolone-resistant Staphylococcus aureus, vancomycin and glycopeptide intermediate Staphylococcus aureus and vancomycin resistant Staphylococcus aureus. Intravenous dosage form developed to treat complicated skin and skin structure infections and has recently completed Phase III studies in India and Phase I studies in USA.

Anisodamine is a naturally occurring atropine derivative that has been isolated, synthesized and characterized by scientists in the People's Republic of China. Anisodamine is a non-specific cholinergic antagonist. Anisodamine has been shown to interact with and disrupt liposome structure which may reflect its effects on cellular membranes. Experimental evidence implicates anisodamine as an anti-oxidant that may protect against free radical-induced cellular damage. Its cardiovascular properties include depression of cardiac conduction and the ability to protect against arrhythmia induced by various agents. Anisodamine is a relatively weak alpha(1) adrenergic antagonist which may explain its vasodilating activity. Its anti-thrombotic activity may be a result of inhibition of thromboxane synthesis. Numerous therapeutic uses of anisodamine have been proposed including treatment of septic shock, various circulatory disorders, organophosphorus (OP) poisoning, migraine, gastric ulcers, gastrointestinal colic, acute glomerular nephritis, eclampsia, respiratory diseases, rheumatoid arthritis, obstructive jaundice, opiate addiction, snake bite and radiation damage protection. The primary therapeutic use of anisodamine has been for the treatment of septic shock. Several mechanisms have been proposed to explain its beneficial effect though most mechanisms are based upon the assumption that anisodamine ultimately acts by an improvement of blood flow in the microcirculation. Preliminary studies suggest another important therapeutic use of anisodamine is for the treatment of OP poisoning. Anisodamine has been employed therapeutically since 1965 in the People’s Republic of China primarily to improve blood flow in circulatory disorders such as septic shock, disseminated intravascular coagulation (DIC) and as an antidote to organophosphate poisoning.

Vasopharm BIOTECH is developing 4-aminotetrahydrobiopterin (ronopterin, VAS 203), a nitric oxide synthase inhibitor, for the treatment of traumatic brain injury. Ronopterin is an allosteric nitric oxide (NO) synthase inhibitor interacting with the tetrahydrobiopterinbinding site of the enzyme. Pre-clinical, proof-of-principle studies using controlled cortical impact showed that VAS203 had significant and positive effects on elevated intracranial pressure (ICP), which contributes to the deleterious consequences of TBI, as well as on neurological outcome measured with behavioural tests. By targeting both cerebral blood vessels and cerebral tissue in a region-specific manner VAS203 represents a completely novel pharmacological approach to TBI that can be administrated in addition to best standard of care. Ronopterin is currently in development for the treatment of traumatic brain injury.In the phase III clinical trial, ronopterin is administered as a 17 mg/kg intravenous infusion over 48 hours (daily dose of 8.5 mg/kg).
