Betaxolol is a competitive, beta(1)-selective (cardioselective) adrenergic antagonist. Betaxolol is used to treat hypertension, arrhythmias, coronary heart disease, glaucoma, and is also used to reduce non-fatal cardiac events in patients with heart failure. (R)-Betaxolol (Dextrobetaxolol) is the R-isomer of Betaxolol (B328000), a cardioselective β1-adrenergic blocker. It is also an antihypertensive and antiglaucoma agent. Dextrobetaxolol had a much weaker affinity at both b1 and b2 receptors than levobetaxolol. Levobetaxolol (Kb=6 nM at b1 and Kb=39 nM at b2 receptors) more potently inhibited functional activities in cells expressing human recombinant b1 and b2 receptors than dextrobetaxolol (Kb=350 and 278 nM, respectively). Likewise, levobetaxolol was a more potent antagonist in isolated tissues than dextrobetaxolol. In functional assays in cultured human NPE cells levobetaxolol (Ki =16.4 nM) was a potent antagonist of isoproterenol-induced cAMP production with dextrobetaxolol (Ki =2.9 uM) being considerably weaker than the latter antagonist. In ocular hypertensive cynomolgus monkeys, levobetaxolol was more effective at reducing IOP than dextrobetaxolol. The results of the study of the pharmacokinetic behavior of the R and S enantiomers of betaxolol following iv and oral administration of the racemate to healthy male subjects failed to reveal any important difference between the pharmacokinetics of the R and S enantiomer of betaxolol. Thus, the pharmacokinetic behavior of racemic betaxolol accurately reflects the behavior of betaxolol enantiomers in this subject group.

Glycitin (4'-Hydroxy-6-Methoxyisoflavone-7-D-Glucoside) is a soy isoflavone. Isoflavone mixtures from soybean containing glycitin exert anti-obese and antidiabetic, antineoplastic, antioxidant effects. Isoflavone supplementation in healthy males may enhance cognitive processes which appear dependent on oestrogen activation. Glycitin underwent hydrolysis of the beta-glycoside moiety and little further biotransformation, leading to high plasma glycitein concentrations.

Talinolol (brand name Cordanurn) is the cardioselective beta-receptor antagonist which has been used for a long time in the treatment of various cardiovascular diseases and in tachyarrhythmia. The mean dosage is 10-20 mg intravenously administered over a period of 3-5 minutes, while the chronic oral dosage for this patient group amounts to 300mg/day. Cordanum eliminates the stimulating effect of catecholamines on the heart for physical and psychoemotional stress. The hypotensive effect is stabilized by the end of 2 weeks of course treatment. Reduces the frequency and severity of angina attacks; Contributes to the limitation of the heart attack zone and reduces the risk of arrhythmia in the presence of myocardial infarction, resulting in a decrease in mortality and the frequency of relapses. In average therapeutic doses, it has a less pronounced effect on the smooth muscles of the bronchi, myometrium, and peripheral arteries compared to non-selective beta-blockers. Talinolol is used in supraventricular (atrial fibrillation and flutter with high ventricular rate, paroxysmal supraventricular 1 tachycardia, sinus tachycardia) as well as ventricular extrasystoles and ventricular tachyarrhythmias. Patients with an increased tonus of the sympathetic nervous system related to sinus tachycardia, exercise-induced arrhythmias, hypertension, hyperthyroidism and coronary heart disease show a particularly positive reaction.

8-Hydroxyquinoline is is a heterocyclic phenol, exhibiting antiseptic, disinfectant and pesticide properties. It is used to prevent and treat vaginal bacterial infections, but the efficacy was not proven in clinical trial. 8-Hydroxyquinoline is used in over-the-counter remedies for diaper rash and oral health care. Its use for veterinary treatment of bacterial an skin infections is not approved by FDA. 8-Hydroxyquinoline acts by inhibition of RNA synthesis and DNA replication by chelating the dissociable cations Mn2 and Mg2 .

Ebastine is an antihistamine which blocks H1-receptors through its carboxylic acid metabolite. Ebastine is indicated for the treatment of allergic rhinitis and chronic idiopathic urticaria.

Pyriproxyfen is a broad-spectrum insect growth regulator with insecticidal activity against public health insect pests: houseflies, mosquitoes and cockroaches. In agriculture and horticulture, pyriproxyfen has registered uses for the control of scale, whitefly, bollworm, jassids, aphids and cutworms. Pyriproxyfen is used on citrus fruit in Israel, South Africa, Spain and Italy. Pyriproxyfen is one of several insecticides used for the control of the red imported fire ant (Solenopsis invicta) in California, USA. Pyriproxyfen has also been considered by WHO for vector control under its Pesticides Evaluation Scheme. It is a potent suppressor of embryogenesis and adult formation of the sweetpotato whitefly, Bemisia tabaci (Gennadius), and the greenhouse whitefly, Trialeurodes vaporariorum (Westwood). Dipping of cotton or tomato seedlings infested with 0 to 1-day-old eggs in 0.1 mg litre−1 resulted in over 90% suppression of egg hatch of both B. tabaci and T. vaporariorum. Pyriproxyfen is registered in the U.S. for flea and tick control in the home and on pets, as well as indoor and outdoor ant and roach control. Formulas include carpet powders, foggers, aerosols, shampoos, bait, and pet collars.

Propoxur (Baygon) is a carbamate insecticide that has recently attracted considerable attention as a possible treatment option for addressing the bedbug epidemic. Propoxur is a non-systemic insecticide with a fast knockdown and long residual effect used against the turf, forestry, and household pests and fleas. The generally accepted mechanism of toxicity for propoxur involves the inhibition of cholinesterase. Propoxur is also used in pest control for other domestic animals, Anopheles mosquitoes, ants, gypsy moths, and other agricultural pests. It can also be used as a molluscicide. Several U.S. states have petitioned the Environmental Protection Agency (EPA) to use propoxur against bedbug infestations, but the EPA has been reluctant to approve indoor use because of its potential toxicity to children after chronic exposure.

Raclopride is a salicylamide neuroleptic, that acts as a selective antagonist of D2 dopamine receptors both in vitro and in vivo. Tritium-labelled raclopride has properties that demonstrate its usefulness as a radioligand for the labelling of dopamine-D2 receptors : 3H-Raclopride has a high affinity for the rat and human dopamine-D2 receptors, the non-specific binding of 3H-raclopride is very low, not exceeding 5% of the total binding and the distribution of the 3H-raclopride binding sites in the brain closely correlates with the dopaminergic innervation. The binding of 3H-raclopride is blocked by dopamine-D2 agonists and antagonists, while the D1 agonist SKF 38393 and the Dl antagonist SCH 23390 have much less potency. The interaction of dopamine with 3H-raclopride binding results in a shallow competition curve, which suggests that 3H-raclopride, similar to other dopamine-D2 radioligands, labels both high and low agonist affinity states of the dopamine-D2 receptor. The in vivo receptor binding studies performed with 3H-raclopride also demonstrate its favorable properties as a dopamine-D2 receptor marker in vivo In contrast to some other compounds used as radioligands, raclopride enters the brain readily and binds with a low component of non-specific binding in all dopamine-rich brain areas. A saturation curve may be achieved in vivo binding studies since injections of increasing concentrations of 3H-raclopride appears to be saturated at concentrations above 25 mkCi (corresponding to approximately 5 nmol/kg). Raclopride antagonizes apomorphine-induced hyperactivity in the rat at low doses (ED50 = 130 nM/kg i.p.) but induces catalepsy only at much higher doses (ED50 = 27 mkM/kg i.p.). Radiolabelled raclopride has been used as a ligand for in vitro and in vivo autoradiography in rat and primate brains. Raclopride C 11 is used with positron emission tomography (PET) as a clinical research tool to determine dopamine type 2 (D 2) receptor density in the human brain under normal and pathological conditions. For example, raclopride C 11 used in PET studies has served to confirm the age-related decrease in striatal dopamine D2 receptor density, which may be associated with a decline in the motor as well as cognitive functions. In patients with Alzheimer's disease, raclopride C 11 may be used to examine neuroreceptor distribution and quantities, which may help in the analysis of degenerative alterations of neuron populations and neuroreceptor systems in patients with this disease. In Huntington's disease, in which degeneration of neostriatal interneurons occurs (postsynaptic to the dopaminergic input), specific binding of raclopride C 11 to D 2 receptors may serve as one of the parameters in predicting performance in cognitive tasks.

Dihydromorphine is a semi-synthetic opioid derived from morphine. dihydromorphine is a moderately strong analgesic and is used clinically in the treatment of pain and is also the active metabolite of dihydrocodeine. Dihydromorphine acts as an agonist at the μ-opioid (mu), δ-opioid (delta) and κ-opioid (kappa) receptors. Dihydromorphone is approved for clinical use in the United States, Europe, and Japan; and sold under the brand name Dilaudid. Similar to morphine, and other morphine derivatives, hydromorphone has a high potential for addiction and abuse and is listed as a Schedule II drug in the United States Controlled Substances Act of 1970 (and similarly regulated in other countries).

(s)-Thalidomide is an enantiomer of immunomodulatory agent Thalidomide. Thalidomide enantiomers are converted to each other in vivo, and Thalidomide contains both left and right-handed isomers in equal amounts. (s)-Thalidomide has proven efficacy in multiple myeloma. s-thalidomide-induced apoptosis associated with increases in I-kB activity, downregulation of NF-kB activity and an increase in Bax: Bcl-2 ratio. In cells cultured with s-thalidomide, there was a four-fold downregulation of the NFkB gene that was associated with a significant decrease in its protein activity.
