Methanesulfonyl fluoride (SNX 001), a very long-acting CNS-selective acetylcholinesterase inhibitor, was studied as a palliative treatment for senile dementia of the Alzheimer type. This drug successfully completed phase I clinical trials where it showed effectively enhance memory in patients with Alzheimer's disease. However, it appears that further studies were discontinued.

Carperidine is a 4-phenylpiperidine derivative that is related to the opioid analgesic drug pethidine. Carperidine is not currently used in medicine. Presumably it has similar effects to other opioid derivatives, such as analgesia, sedation, nausea and respiratory depression, however unlike most opioid derivatives it is not specifically listed as an illegal drug, although it is on the drugs and poisons lists of some countries, and would probably be regarded as a controlled substance analogue of pethidine on the grounds of its related chemical structure in some jurisdictions such as the USA, Canada, Australia and New Zealand.

CE-224535 is a potent, highly selective, orally bioavailable, non-competitive antagonist of the human P2X7 receptor. Pre-clinical pharmacokinetic studies with CE-224535 indicate limited CNS penetration. In clinical trials, CE-224535 failed to demonstrate efficacy in a 2-week study of knee pain in osteoarthritis or a 12-week study in patients with rheumatoid arthritis. CE-224535 is safe and well tolerated after administration of up to 1600 mg as a single dose or 600 mg every 12 hours for 14 days in healthy subjects and 500 mg every 12 hours for 2 weeks in subjects with osteoarthritis of the knee and 12 weeks in rheumatoid arthritis patients with an inadequate response to methotrexate.

Clazolam (isoquinazepon) is a fuzed benzodiazepine drug developed by Sandoz in the 1960s. The drug is claimed to have anxiolytic properties, which are manifested in a reduction of cramping, antagonism of amphetamine, and by inhibition of spinal reflexes.

Benzpiperylone was studied as a synthetic anti-inflammatory drug. Information about the nowadays use of this compound is not available.

Proquinolate is a quinoline derivative patented by Norwich Pharmacal Co. as an antiparasitic agent used to control coccidiosis in the chicken industry.

Doxenitoin is a phenytoin-like structure, the only difference being reduction of the carbonyl at the 2-position to a methylene group. This drug has significant anticonvulsant potency. It was developed as an antiepileptic agent.

Iosefamic Acid is triiodoisophthalamic acid derivative patented by Mallinckrodt Chemical Works as x-ray contrast agent for imaging in the biliary and urinary systems and in vasography.

Amotriphene (Myordil, WIN 5494) is a coronary dilator and cardiac antiarrhythmic properties. It has potential value in the treatment of angina-like conditions and the milder cardiac arrhythmias. Amotriphene binds to α‐adrenergic receptors.

There is no information about biological and/or pharmacological application of phenbutazone sodium glycerate.
