CHEMICAL (ACHIRAL)
Conditions:
Omidenepag isopropyl, a prodrug, is hydrolyzed in the eye to the active form (Omidenepag) which functions as a selective, nonprostaglandin, prostanoid EP2 agonist, has been developed by Ube Industries and Santen Pharmaceutical as an ophthalmic solution (EYBELIS®) for the treatment of glaucoma and ocular hypertension. Omidenepag isopropyl increases the outfow of aqueous humor via both the uveoscleral outfow and the trabecular outfow pathways, resulting in potent and stable reduction in intraocular pressure (IOP). In September 2018, omidenepag isopropyl ophthalmic solution 0.002% was approved in Japan for the treatment of glaucoma and ocular hypertension. On September 22, 2022, the FDA approved Santen’s Omlonti (omidenepag isopropyl), for the reduction of elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension.

Targets:
Mibefradil is a calcium channel blocker, chemically unlike other compounds in the class, that was approved by the Food and Drug Administration (FDA), U.S.A. in June 1997 for the treatment of patients with hypertension and chronic stable angina. Shortly following its introduction, mibefradil was withdrawn from the market in the U.S.A. as well as in Europe. The reason for the voluntary withdrawal of the drug by Roche laboratories was claimed to be the result of new information about potentially harmful interactions with other drugs.
Mibefradil is calcium channel blocker with moderate selectivity for T-type Ca2+ channels displaying IC50 values of 2.7 uM and 18.6 uM for T-type and L-type channels respectively. Mibefradil is a tetralol calcium channel blocking agent that inhibits the influx of calcium ions across both the T (low-voltage) and L (high-voltage) calcium channels of cardiac and vascular smooth muscle, with a greater selectivity for T channels. Vasodilation occurs in vascular smooth muscle, causing a decrease in peripheral vascular resistance and a resulting decrease in blood pressure. Mibefradil causes a slight increase in cardiac output during chronic dosing. Mibefradil slows sinus and atrioventricular (AV) node conduction, producing a slight reduction in heart rate and a slight increase in the PR interval. It has also been shown to slightly lengthen the corrected sinus node recovery time and AH interval and to raise the Wenckebach point. The mechanism by which mibefradil reduces angina is not known, but is thought to be attributed to a reduction in heart rate, total peripheral resistance (afterload), and the heart rate-systolic blood pressure product at any given level of exercise. The result of these effects is a decrease in cardiac workload and myocardial oxygen demand. Mibefradil has been repurposed from an abandoned antihypertensive to a targeted solid tumor treatment, and it has been rescued from drug-drug interactions by using short-term dose exposure. Tau is using the early success of mibefradil as a proof of concept to build a platform technology of Cav3 blockers for broad antitumor applications in combination with new targeted cancer therapies, well-established.

Class (Stereo):
CHEMICAL (RACEMIC)
Conditions:
Iofetamine hydrochloride I-123 is a radiopharmaceutical for cerebral perfusion imaging. lofetamine is the N-isopropyl derivative of amphetamine with iodine 123(1123) at the para position to serve
as the tracer. This configuration was systematically
derived by Winchell et al. to provide sufficient brain
uptake and retention for brain imaging, which typically
requires an acquisition time of 25-40 minutes. After
experimental intraarterial injection the drug has a high
extraction ratio (> 90 percent) in the brain. Iofetamine hydrochloride I-123 permits cerebral blood perfusion imaging with single photon emission computed tomography (SPECT). Iofetamine is an amphetamine analog that is rapidly taken up by the lungs, then redistributed principally to the liver and brain. The precise mechanism of localization has not been determined, but is believed to result from nonspecific receptor binding. Brain uptake peaks at 30 minutes postinjection and remains relatively constant through 60 minutes. The drug is metabolized and excreted in the urine, with negligible activity remaining at 48 hours. When compared with CT in stroke patients, visualization may be performed sooner after symptom onset and a larger zone of involvement may be evident with iofetamine. Localization of seizure foci and diagnosis of Alzheimer's disease may also be possible. As CT has revolutionized noninvasive imaging of brain anatomy, SPECT with iofetamine permits routine cerebral blood flow imaging. Iofetamine hydrochloride I-123 under the brand name Spectamine was approved for use in the United States as a diagnostic aid in determining the localization of and in the evaluation of non-lacunar stroke and complex partial seizures, as well as in the early diagnosis of Alzheimer's disease in 1987. However it was discontinued in USA.

CHEMICAL (ACHIRAL)
Targets:
Propantheline is an antimuscarinic agent used for the treatment of excessive sweating (hyperhidrosis), cramps or spasms of the stomach, intestines (gut) or bladder, and involuntary urination (enuresis). It can also be used to control the symptoms of irritable bowel syndrome and similar conditions. Propantheline is one of a group of antispasmodic medications which work by blocking the action of the chemical messenger acetylcholine, which is produced by nerve cells, to muscarinic receptors present in various smooth muscular tissues, in places such as the gut, bladder, and eye. Normally, the binding of acetylcholine induces involuntary smooth muscular contractions. Varying degrees of drying of salivary secretions may occur as well as decreased sweating. Ophthalmic side effects include blurred vision, mydriasis, cycloplegia, and increased ocular tension. Other reported adverse reactions include urinary hesitancy and retention, tachycardia, palpitations, loss of the sense of taste, headache, nervousness, mental confusion, drowsiness, weakness, dizziness, insomnia, nausea, vomiting, constipation, bloated feeling, impotence, suppression of lactation, and allergic reactions or drug idiosyncrasies including anaphylaxis, urticaria and other dermal manifestations.
