Source URL:
First approved in 1975

Class (Stereo):
CHEMICAL (ACHIRAL)



Clotrimazole is an anti-fungal medicine indicated for the treatment of vaginal yeast infections and tinea. It can be used either in combination with other drugs (betamethasone dipropionate) or alone, in form of topical or vaginal cream. The drug exerts its action by inhibiting lanosterol demethylase thereby affecting the growth of fungi.

Class (Stereo):
CHEMICAL (ACHIRAL)



Tetracaine (INN, also known as amethocaine; trade name Pontocaine. Ametop and Dicaine) is a potent local anesthetic of the ester group. It is mainly used topically in ophthalmology and as an antipruritic, and it has been used in spinal anesthesia. Tetracaine blocks sodium ion channels required for the initiation and conduction of neuronal impulses thereby affecting local anesthesia. In biomedical research, tetracaine is used to alter the function of calcium release channels (ryanodine receptors) that control the release of calcium from intracellular stores. Tetracaine is an allosteric blocker of channel function. At low concentrations, tetracaine causes an initial inhibition of spontaneous calcium release events, while at high concentrations, tetracaine blocks release completely.

Conditions:

Dibucaine is used as a local anesthetic for surface anesthesia. It is one of the most potent and toxic of the long-acting local anesthetics and its parenteral use is restricted to spinal anesthesia. Dibucaine is used to temporarily relieve pain and itching due to: hemorrhoids or other anorectal disorders, sunburn, minor burns, minor cuts; scrapes, insect bites, minor skin irritation. This drug acts via blocking of nerve impulses by decreasing the neuronal membrane's permeability to sodium ions through sodium channel blocking. This reversibly stabilizes the membrane and inhibits depolarization, resulting in the failure of a propagated action potential and subsequent conduction blockade.
Zinc monocarbonate (Zinc Carbonate) is an inorganic salt. In the United States, Zinc Carbonate may be used as an active ingredient in OTC drug products. When used as an active drug ingredient, the established name is Zinc Carbonate. Zinc monocarbonate is generally recognized as safe by FDA. It is used as skin protectant active ingredient. Zinc carbonate was found to retard the degradation of some poly(lactide-co-glycolide) (PLG) microspheres in vivo and in vitro. Adding Zinc Carbonate is essential during the preparation of PLGA microspheres. It can remarkably improve the stability of drugs in the acid microenvironment inside PLGA microspheres.
Caffeine is a methylxanthine alkaloid found in the seeds, nuts, or leaves of a number of plants native to South America and East Asia that is structurally related to adenosine and acts primarily as an adenosine receptor antagonist with psychotropic and anti-inflammatory activities. Upon ingestion, caffeine binds to adenosine receptors in the central nervous system (CNS), which inhibits adenosine binding. This inhibits the adenosine-mediated downregulation of CNS activity; thus, stimulating the activity of the medullary, vagal, vasomotor, and respiratory centers in the brain. The anti-inflammatory effects of caffeine are due the nonselective competitive inhibition of phosphodiesterases. Caffeine is used by mouth or rectally in combination with painkillers (such as aspirin and acetaminophen) and a chemical called ergotamine for treating migraineheadaches. It is also used with painkillers for simple headaches and preventing and treating headaches after epidural anesthesia. Caffeine creams are applied to the skin to reduce redness and itching in dermatitis. Healthcare providers sometimes give caffeine intravenously (by IV) for headache after epidural anesthesia, breathing problems in newborns, and to increase urine flow. In foods, caffeine is used as an ingredient in soft drinks, energy drinks, and other beverages.

Class (Stereo):
CHEMICAL (ACHIRAL)

METHYLPARABEN SUBEROHYDROXAMIC ACID PHENYL ESTER (more known as Remetinostat), a histone deacetylase (HDAC) inhibitor, was developed for the treatment of cutaneous T cell lymphoma (CTCL). This drug is participating in phase II clinical trial to evaluate the efficacy, safety, and tolerability to skin lesions in patients with early-stage cutaneous T-cell lymphoma. In May 2019 was announced the positive results from phase II trial of remetinostat in basal cell carcinoma (BCC) patients. Initial results suggest that remetinostat gel offers a potentially effective and well-tolerated, non-surgical intervention for the treatment of localized BCCs. The unique design of remetinostat enables topical application, making it active only in the skin. As soon as it reaches the blood stream, it is degraded, avoiding the side effects associated with other HDAC inhibitors. Besides, remetinostat was studied as the treatment of plaque psoriasis; however, this study was discontinued.

Bicyclomycin has been used to treat diarrhea in humans and bacterial diarrhea in calves and pigs and is marketed by Fujisawa (Osaka, Japan) under the trade name Bicozamycin. This drug is the selective inhibitor of rho, a member of the RecA-type ATPase class of enzymes that use nucleotide contacts to couple oligonucleotide translocation to ATP hydrolysis.

Emitefur or BOF-A2 is a fluorinated pyrimidine antimetabolite exerting antineoplastic properties. It is a compound composed of 5-fluorouracil (5-FU) and 3-cyano-2,6-dihydroxypyridine (CNDP), an inhibitor of 5-FU degradation by dihydrouracil dehydrogenase in order to prolong the blood 5-FU level as well as increase selective toxicity to a tumor. Emitefur demonstrated clinical activity in preliminary studies in Japan. Emitefur development for the treatment of solid tumors has been discontinued.

Targets:

LAROTAXEL is a taxoid with potential antineoplastic activity. It prevents microtubule depolymerization, thereby inhibiting cell proliferation. It displays a broad spectrum of antitumor activity in vitro and in vivo, including activity against P-glycoprotein expressing tumors. LAROTAXEL was in phase III clinical trials for the treatment of breast cancer, pancreatic cancer, and bladder cancer. However, its development was discontinued.
