Inocoterone
Inocoterone (; developmental code name RU-29294) is a steroid-like nonsteroidal antiandrogen (NSAA) that was never marketed. An acetate ester, inocoterone acetate, shows greater antiandrogen activity and was developed as a topical medication for the treatment of acne but showed only modest effectiveness in clinical trial Clinical trials are prospective biomedical or behavioral research studies on human subject research, human participants designed to answer specific questions about biomedical or behavioral interventions, including new treatments (such as novel v ...s and similarly was never marketed.

Inocoterone Acetate
Inocoterone acetate () (developmental code names RU-38882, RU-882) is a steroid-like nonsteroidal antiandrogen (NSAA) that was developed for topical administration to treat acne but was never marketed. It is the acetate ester of inocoterone, which is less potent in comparison. Inocoterone acetate is actually not a silent antagonist of the androgen receptor but rather a weak partial agonist, similarly to steroidal antiandrogens like cyproterone acetate. Inocoterone acetate was investigated for the treatment of acne but showed only modest (albeit statistically significant) efficacy in clinical trials. A reduction of 26% of lesions was observed in males treated with the drug after 16 weeks (~3.7 months). However, this is notably far less than that achieved with other agents such as benzoyl peroxide or antibiotics, which produce 50–75% reductions within 2 months. Similar poor results with the topical route have disappointingly been found for other antiandrogens such as cyproteron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topical Administration
A topical medication is a medication that is applied to a particular place on or in the body. Most often topical medication means application to body surfaces such as the skin or mucous membranes to treat ailments via a large range of classes including creams, foams, gels, lotions, and ointments. Many topical medications are epicutaneous, meaning that they are applied directly to the skin. Topical medications may also be inhalational, such as asthma medications, or applied to the surface of tissues other than the skin, such as eye drops applied to the conjunctiva, or ear drops placed in the ear, or medications applied to the surface of a tooth. The word ''topical'' derives from Greek τοπικός ''topikos'', "of a place". Justification Topical drug delivery is a route of administering drugs via the skin to provide topical therapeutic effects. As skin is one of the largest and most superficial organs in the human body, pharmacists utilise it to deliver various drugs ...

Delanterone
Delanterone () (developmental code name GBR-21162), also known as 1α-methylandrosta-4,16-dien-3-one, is a steroidal antiandrogen described as an anti-acne agent which was never marketed. The compound showed poor efficacy as an antiandrogen ''in vivo'' in animals, suggestive of low activity or a short terminal half-life, and likely in relation to this was not further developed. It was described and characterized in the literature in 1977. See also * Steroidal antiandrogen A steroidal antiandrogen (SAA) is an antiandrogen with a steroidal chemical structure. They are typically antagonists of the androgen receptor (AR) and act both by blocking the effects of androgens like testosterone and dihydrotestosterone (DH ... * List of steroidal antiandrogens References Androstanes Anti-acne preparations Cyclopentenes Steroidal antiandrogens {{dermatologic-drug-stub ...

Anti-acne Preparations
Acne, also known as ''acne vulgaris'', is a long-term skin condition that occurs when dead skin cells and oil from the skin clog hair follicles. Typical features of the condition include blackheads or whiteheads, pimples, oily skin, and possible scarring. It primarily affects skin with a relatively high number of oil glands, including the face, upper part of the chest, and back. The resulting appearance can lead to anxiety, reduced self-esteem, and, in extreme cases, depression or thoughts of suicide. Susceptibility to acne is primarily genetic in 80% of cases. The roles of diet and cigarette smoking in the condition are unclear, and neither cleanliness nor exposure to sunlight appear to play a part. In both sexes, hormones called androgens appear to be part of the underlying mechanism, by causing increased production of sebum. Another common factor is the excessive growth of the bacterium ''Cutibacterium acnes'', which is present on the skin. Treatments for acne are ava ...

Secondary Alcohols
In chemistry, an alcohol is a type of organic compound that carries at least one hydroxyl () functional group bound to a saturated carbon atom. The term ''alcohol'' originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. An important class of alcohols, of which methanol and ethanol are the simplest examples, includes all compounds which conform to the general formula . Simple monoalcohols that are the subject of this article include primary (), secondary () and tertiary () alcohols. The suffix ''-ol'' appears in the IUPAC chemical name of all substances where the hydroxyl group is the functional group with the highest priority. When a higher priority group is present in the compound, the prefix ''hydroxy-'' is used in its IUPAC name. The suffix ''-ol'' in non-IUPAC names (such as paracetamol or cholesterol) also typically indicates that the substance is an alcohol. However, some ...

Topilutamide
Topilutamide, known more commonly as fluridil and sold under the brand name Eucapil, is an antiandrogen medication which is used in the treatment of pattern hair loss in men and women. It is used as a topical medication and is applied to the scalp. Topilutamide belongs to a class of molecules known as perfluoroacylamido-arylpropanamides. Topilutamide is a nonsteroidal antiandrogen (NSAA), or an antagonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). Topilutamide was introduced for medical use in 2003. It is marketed only in the Czech Republic and Slovakia. The patent for Topilutamide expired in 2020. Medical uses Topilutamide is used as a topical medication in the treatment of pattern hair loss in men and women. Topilutamide is approved for cosmetic use in Europe but has not received FDA approval nor approval by the EMA for the treatment of androgenetic alopecia.
