CHEMICAL (RACEMIC)

Profadol is a pyrrolidine derivative patented in the 1960s by pharmaceutical company Parke-Davis as opioid analgesic. Profadol acts as a mixed agonist-antagonist of the μ-opioid receptor and in preclinical studies, Profadol precipitates abstinence in morphine-dependent monkeys and can reverse pethidine- induced narcosis in nondependent monkeys. In morphine-dependent human subjects, Profadol was also found to pre¬cipitate acute abstinence syndromes, with a potency 40 to 50 times less than that of nalorphine. Profadol, unlike other morphine-antagonists, does not produce nalorphine-like subjective effects. Over a fourfold range of doses, this drug was found to produce subjective effects indistinguishable from those of morphine. Also unlike other morphine-antagonists, profadol is quite active on the "classical" rodent tests for analgesia. It is about 1.3 times as potent as pethidine on the mouse hot-plate test, and about four times as potent on the rat tail-pressure test.

Cizolirtine is a potent analgesic in mice and rats, with an efficacy superior to that of aspirin and other nonsteroid anti-inflammatory drugs. Recent studies have shown that the analgesic effect of cizolirtine could be related, at least partially, to an inhibition of spinal substance P and calcitonin gene-related peptide release. Cizolirtine has been in clinical trials for the treatment of pain and overactive bladder. Reported adverse events are: dry mouth, dizziness, nausea, vomiting, blurred vision.

Tazomeline (also known as LY 287041), a neuropsychiatric agent, is a muscarinic M1 acetylcholine receptor agonist that was studied in patients with cognitive dysfunction. Tazomeline participated in clinical trials for the treatment of Alzheimer’s disease and dementia. However, all these studied were discontinued for unknown reasons.

Gamfexine (WIN 1344) was introduced in the literature in 1966 as an anti-depressant. Although it was reported to be effective in the treatment of withdrawal in schizophrenia, it worsened psychotic symptoms.

Nitromiphene (NIT; CI 628) is a triarylethylene antiestrogen shown to be effective in treatment of experimental breast cancer. Nitromiphene is one of the earliest nonsteroidal selective estrogen receptor modulators (SERMs). It is an anti-estrogen capable to translocate the estrogen receptor to the nucleus and to induce the replenishment of the cytosol receptor. Nitromiphene inhibited the uptake of [3H]-estradiol in rat whole homogenates and isolated cell nuclei tissues and the pituitary, and inhibited estradiol-induced female sexual behavior. Nitromiphene has thus been shown to suppress the growth of chemically induced and ransplantedmammary tumors in rodents. Also, Nitromiphene was shown to have potent, prolonged antiuterotropic effects in immature rats. Nitromiphene has been shown to undergo conversion to demethyl Nitromiphene (CI628M), a phenolic metabolite which had greater affinity for estrogen receptors and greater biological potency in vitro than did Nitromiphene. However, the in vivo antiestrogenic effects of Nitromiphene and demethyl Nitromiphene were similar, possibly due to facile O-demethylation of the former compound after administration.

Arimoclomol (INN; originally codenamed BRX-345, which is a citrate salt formulation of BRX-220) is an experimental drug developed by a biopharmaceutical company CytRx Corporation. In 2011 the worldwide rights to arimoclomol were bought by Danish biotech company Orphazyme ApS. The European Medicines Agency (EMA) and U.S. Food & Drug Administration (FDA) granted orphan drug designation to arimoclomol as a potential treatment for Niemann-Pick type C in 2014 and 2015 respectively. Arimoclomol is believed to function by stimulating a normal cellular protein repair pathway through the activation of molecular chaperones. Since damaged proteins, called aggregates, are thought to play a role in many diseases, CytRx believes that arimoclomol could treat a broad range of diseases.

Droloxifene, a derivative of the triphenylethylene drug tamoxifen, is a novel selective estrogen receptor modulator (SERM). Droloxifene also exhibits more rapid pharmacokinetics, reaching peak concentrations and being eliminated much more rapidly than tamoxifen. Its higher affinity to the estrogen receptor, higher anti-estrogenic to estrogenic ratio, more effective inhibition of cell growth and division in estrogen receptor-positive cell lines, and lower toxicity give it theoretical advantages over tamoxifen in the treatment of human breast cancer. Short-term toxicity was generally mild, and similar to that seen with other antiestrogens. Droloxifene appears active and tolerable. It may have a particular role in situations in which rapid pharmacokinetics, or an increased antiestrogenic to estrogenic ratio, are required. Droloxifene may also be a potentially useful agent for the treatment of postmenopausal osteoporosis because it can prevent estrogen deficiency-induced bone loss without causing uterine hypertrophy. Droloxifene may have an effect on bone and breast tissue because it induces apoptosis. Droloxifene has an anti-implantation effect in rats, and the effect appears to be not completely due to its anti-estrogenic activity.
