FERROSOFERRIC OXIDE is a black ore of iron. It is a coloring matter used in the pharmaceutical industry as a coating pigment.

Erythromycin cyclocarbonate (Davercin) is a first generation semi-synthetic erythromycin. It is active against Gram-positive and some Gram-negative microorganisms. Davercin shows comparable or better in vitro potency, low host toxicity and improved pharmacokinetics compared with erythromycin. It is approved for the treatment of acne, atypical pneumonia (caused by Mycoplasma pneumoniae, Chlamydia pneumoniae, Legionella pneumophila), whooping cough (treatment and prevention), urethritis (caused by Ureaplasma urealyticum and Chlamydia trachomatis), gastrointestinal infection caused by Campylobacter spp., short-term infections of the skin and soft tissues (e.g. acne, staphylococcal dermatitis). In streptococcal infections, diphtheria, gonorrhea, early syphilis in patients who are allergic to penicillin, and in the prevention of bacterial endocarditis before the planned dental procedures. Adverse effects are: nausea, vomiting, abdominal pain, diarrhea, skin allergic reactions.

Resorcinol Acetate is used as an ingredient to reduce the number of acne blemishes, acne pimples, blackheads, and whiteheads. In the United States, anti-acne agents are regulated as Over-the-Counter (OTC) drug ingredients. Resorcinol Acetate is also used to enhance the appearance and feel of hair, by increasing hair body, suppleness, or sheen, or by improving the texture of hair that has been damaged physically or by chemical treatment and to enhance the appearance of dry or damaged skin by reducing flaking and restoring suppleness.

Resorcinol is a benzenediol. Resorcinol is commonly used in hair dyes and acne medication. Resorcinol works by breaking down rough, scaly, or hardened skin. Resorcinol also disinfects the skin to help fight infection. Resorcinol topical (for the skin) is used to treat pain and itching caused by minor cuts and scrapes, burns, insect bites, poison ivy, sunburn, or other skin irritations. Resorcinol topical is also used to treat acne, eczema, psoriasis, seborrhea, corns, calluses, warts, and other skin disorders. Resorcinol is included in the FDA final rule list of all permitted active ingredients for OTC topical acne products. Permitted combination active ingredient product - Resorcinol in 2 percent concentration in combination with sulfur in concentrations of between 3 and 8 percent. In oxidative hair dyes, resorcinol is regulated to 5% or below in practice, however, many manufacturers limit the level of free resorcinol in oxidative hair dyes to 1.25%. Resorcinol is limited to 0.5% in shampoos and hair lotions. Resorcinol is usually present in anti-acne preparations at a maximum concentration of 2%. The concentration of resorcinol can be much higher in peels, in some cases around 50%. Jessner’s solution (resorcinol in ethyl alcohol, 14% w/v; lactic acid, 14%; and salicylic acid, 14%) is commonly used in chemical peeling. A specialized medical use of resorcinol is in biological glues (gelatin–resorcinol–formaldehyde glue) for cardiovascular surgery, in particular aortic operations.

ASC-J9, also known dimethylcurcumin, is an androgen receptor (AR) degradation enhancer, it suppresses AR function via selective interruption between androgen receptors (ARs) and its selective co-activators (ARA55 or ARA70). This drug was successfully passed phase II clinical trial for topical application to treat the facial acne. In addition, ASC-J9 participated in the preclinical experiments to suppress prostatitis by altering the autoimmune response induced by CD4 T cell recruitment. In combination with sorafenib was shown, that ASC-J9 suppressed the hepatocellular carcinoma (HCC) progression via altering the pSTAT3-CCL2/Bcl2 signals.

Lupeol, a biologically active dietary triterpenoid, is found in many medicinal plants and different fruits such as olives, mangos, and strawberries. Lupeol exhibits a wide spectrum of pharmacological properties including anti-inflammatory, anti-cancer, anti-diabetic, anti-microbial, cardioprotective, and hepatoprotective activities. Lupeol inhibits LPS-induced microglial neuroinflammation via the P38-MAPK and JNK pathways and has therapeutic potential to treat various neuroinflammatory disorders. Lupeol possesses antiskin tumor-promoting effects in CD-1 mouse and inhibits conventional as well as novel biomarkers of tumor promotion. It strongly suppressed lipogenesis by modulating the IGF-1R/phosphatidylinositide 3 kinase (PI3K)/Akt/sterol response element-binding protein-1 (SREBP-1) signaling pathway in SEB-1 sebocytes, and reduced inflammation by suppressing the NF-κB pathway in SEB-1 sebocytes and HaCaT keratinocytes. Lupeol exhibited a marginal effect on cell viability and may have modulated dyskeratosis of the epidermis. These results demonstrate the clinical feasibility of applying lupeol for the treatment of acne.

Dequalinium salicylate is a bisquanternary quinolinium antiseptic which kills many gram-positive and gram-negative bacteria. Dequalinium Salicylate have antibacterial (mediated by Dequalinium action) and anti-inflammatory activities (mediated by Salicylic acid action). Dequalinium has an antiseptic effect against a wide range of bacteria, yeasts, and some fungi and viruses. It kills the micro-organisms associated with various mild infections of the mouth and throat. Salicylic acid have direct anti-inflammatory activity mediated by inhibition of both types of cyclo-oxygenases (COX-1 and COX-2) to decrease the formation of precursors of prostaglandins and thromboxanes from arachidonic acid.

Talarozole (formerly R115866) is a new highly potent and selective azole derivative, which inhibits cytochrome-P450-dependent all-trans-retinoic acid catabolism by blocking the cytochrome P450 enzyme isoform CYP26, a retinoic acid hydroxylase. It is in clinical development for the treatment of psoriasis and acne. However, no local pharmacokinetic data on the diffusion behaviour of talarozole in the skin itself are available. As topical application might be an interesting alternative to oral therapy because of the reduced systemic side effects. The distribution of talarozole within the skin was investigated: 80% was located in the epidermis, while the remaining 20% was found in the dermis. The epidermal concentration of talarozole achieved after a single topical application was sufficiently high to enable the potential induction of local retinoid-like effects.

Schisandrin A is a bioactive lignan occurring in the fruits of plants of the Schisandra genus that have traditionally been used in Korea for treating various inflammatory diseases. Schisandrin A inhibits dengue viral replication via upregulating antiviral interferon responses through STAT signaling pathway. Schisandrin A represents a potential antiviral agent to block DENV replication in vitro and in vivo. Schisandrin A has been widely reported as being very effective for the treatment of liver disease. The hepatoprotective mechanisms of schisandrin A may include activation of autophagy flux and inhibition of apoptosis.

Indoleacetic acid is the most abundant and basic plant hormone of auxin class. In plants, it plays a key role in both roots and shoots development. In mammals, indoleacetic acid is often produced by the action of gut bacteria. Elevated levels of indoleacetic acid have been found in the urine of patients with phenylketonuria. Indoleacetic acid was evaluated as a photosensitizer for acne treatment.
