Class (Stereo):
CHEMICAL (ABSOLUTE)



Cadazolid is a new antibiotic in development for the treatment of Clostridium difficile-associated diarrhea. Cadazolid is active against all (including linezolid- and moxifloxacin-resistant) Clostridium difficile strains. In phase I and II clinical trials, cadazolid was shown to be safe, well tolerated, and efficacious positioning itself as a potential future viable therapeutic option for CDI. Using a series of macromolecular labeling, in vitro transcription/translation, and topoisomerase studies, it was determined that protein synthesis inhibition via the oxazolidinone moiety is the primary mechanism of action of cadazolid. Cadazolid is in phase III clinical trials by Actelion Pharmaceuticals for the treatment of Clostridium difficile infection. The US FDA has designated cadazolid as both a Qualified Infectious Disease Product (QIDP) and a Fast Track development program for this indication.

INN:halofenate

Class (Stereo):
CHEMICAL (RACEMIC)

Halofenate (MK-185) was invented as a hypolipidemic and hypouricemic agent. It was shown that halofenate lower serum triglycerides and uric acid in patients with a variety of hyperlipidemias. Treatment of dyslipidemic type 2 diabetic patients also showed triglyceride lowering and, surprisingly, significant reductions in plasma glucose and insulin. Halofenate is a selective PPAR-γ modulator (SPPARγM). SPPARγMs are believed to bind in distinct manners to the ligand-binding pocket of PPAR-γ, leading to altered receptor conformational stability and resulting in distinct patterns of gene expression. Thus, was suggested that halofenate hold promising therapeutic potential in the treatment of type 2 diabetes, without the side effects. However, information about the current use of this compound is not available.

CHEMICAL (ACHIRAL)

Chloracyzine is phenothiazine derivative with vasodilatory activity. Chloracyzine produced a decrease in myocardial oxygen consumption accompanied by a reduction in coronary blood flow preceded by transient coronary dilatation. Chloracyzine produced an insignificant increase in arterial pressure; heart rate increased slightly in the open-chest experiments but not in the isolated heart. It is suggested that reduced oxygen uptake after chloracyzine is realized through improved efficiency in the use of oxygen.

Class (Stereo):
CHEMICAL (RACEMIC)

Cimoxatone is a fully reversible inhibitor selective for the A form of monoamine oxidase. Oral administration of Cimoxatone increased brain noradrenaline, dopamine, and serotonin and decreased DOPAC , 5-HIAA, and 3-methoxy-4-hydroxyphenylethylene glycol sulfate.

Class (Stereo):
CHEMICAL (ACHIRAL)

Bucrylate (isobutyl cyanoacrylate) is a liquid tissue adhesive for transcatheter embolization. It is used in radiological and endoscopic interventions to occlude vessels and to stop bleedings. In comparison with sponges, coils and plugs, bucrylate is inexpensive and achieves immediate, irreversible and complete occlusion of the vessel irrespective of coagulation deficiencies.

Zearalenone (ZEN) is a toxic non-steroidal mycoestrogen produced by fungi that widely contaminate agricultural products, eliciting estrogenic responses by mimicking sex steroid hormones. Zearalenone is biosynthesised through a polyketide pathway by a variety of Fusarium fungi including Fusarium graminearum (Gibberella zeae), Fusarium culmorum, Fusarium equiseti, Fusarium crookwellense, Fusarium cerealis and Fusarium semitectum. Zearalenone and its derivatives share similar molecular mechanisms and activity with estrogens. They interact with the estrogen receptors (ERa and ERb) leading to functional and morphological changes in the reproductive system in both animals and humans. Zearalenone exposure is associated with the estrogenic syndrome and infertility in animals and premature thelarche and precocious puberty in girls. In animal models, it was found that prepubertal exposure to a low dose of Zearalenone, decreased breast cancer risk. When prepubertal rats were treated with 20 lg (1 mg ⁄ kg body weight) of Zearalenone, a significant reduction of both the incidence and multiplicity of DMBA-induced mammary tumours was noted. Zearalenone has been used to treat postmenopausal symptoms in women.

Class (Stereo):
CHEMICAL (ABSOLUTE)



PGD2 (Prostaglandin D2) is a major cellular regulator, has been shown to bind different receptors: D prostanoid receptor (DP) and chemoattractant receptor-homologous molecule expressed on Th2 cells (CRTH2). PGD2 reportedly inhibits platelet aggregation, the proliferation of cells, and activation of neutrophils. This compound is also a potent vasodilator that also relaxes smooth muscle but causes contraction of the bronchial airways. PGD2 promotes T cell migration via CRTH2 and aggravates asthma. In contrast, there have been some studies suggesting that PGD2 exerts anti-inflammatory effects via DP, such as inhibiting the migration and activation of neutrophils, basophils, dendritic cells and T cells. Elevated levels of prostaglandin D2 (PGD2) have been shown to be present in the bald scalp of androgenic alopecia (AGA) patients and was suggested the PGD(2)-GPR44 pathway as a potential target for treatment. Also was revealed, that PGD2 might be a new target for asthma therapy, PGD2 in serum and BALF were lower in the treated group than in the untreated group.

Hyodeoxycholic acid, also known as HDCA, is a secondary bile acid. Natural 6alpha-hydroxylated bile acids are receptor-specific activators of nuclear liver X receptor alpha (LXRalpha), a nuclear receptor regulating the expression of the cholesterol 7alpha-hydroxylase gene. AHRO-001 (Hyodeoxycholic acid) is in phase I clinical trials for the treatment of atherosclerosis. Through a complex signaling processes utilizing LXR receptors, the compound is designed to increase the efficiency of cholesterol efflux using the HDL cells, which act on all cholesterol in the arterial circulation as well as in the lipid core of plaque deposits in the artery walls. Use of AHRO-001 has shown no adverse effects on morbidity, mortality or toxicity and has been well tolerated at high doses.
