Bacitracin is a mixture of related cyclic polypeptides produced by organisms of the licheniformis group of Bacillus subtilis var Tracy. As a polypeptide, toxic, and difficult to use chemical, bacitracin doesn't work well orally, however is very effective topically. Bacitracin exerts pronounced antibacterial action in vitro against a variety of gram-positive and a few gram-negative organisms. However, among systemic diseases, only staphylococcal infections qualify for consideration of bacitracin therapy. Bacitracin is composed of a mixture of related compounds with varying degrees of antibacterial activity. Notable fractions include bacitracin A, A1, B, B1, B2, C, D, E, F, G, and X. Bacitracin A has been found to have the most antibacterial activity. Bacitracin intereferes with the dephosphorylation of the 55-carbon, biphosphate lipid transport molecule C55-isoprenyl pyrophosphate (undecaprenyl pyrophosphate), which carries the building blocks of the peptidoglycan bacterial cell wall outside the inner membrane for construction. Bacitracin binds divalent transition metal ions (Mn(II), Co(II), Ni(II), Cu(II), and Zn(II)) which binds and oxidatively cleave DNA. Used for the treatment of infants with pneumonia and empyema caused by staphylococci shown to be susceptible to the drug. Also used in ointment form for topical treatment of a variety of localized skin and eye infections, as well as for the prevention of wound infections. Used against gram positive bacteria. Bacitracin is also used as an inhibitor of proteases and other enzymes. However, specific activity of bactracin's inhibition of protein disulfide isomerase has been called into question.

Pipotiazine (Piportil), also known as Pipothiazine, is a typical antipsychotic of the phenothiazine class used in the United Kingdom and other countries for the treatment of schizophrenia. Its properties are similar to those of chlorpromazine. Piportil® L4 (pipotiazine palmitate) is the palmitic ester of pipotiazine, a piperidine phenothiazine with antipsychotic properties and weak sedative activity. The esterification of pipotiazine is responsible for its prolonged duration of action. The onset of action appears usually within the first 2 to 3 days after injection and the effects of the drug on psychotic symptoms are significant within one week. Improvement in symptomatology lasts from 3 to 6 weeks, but adequate control may frequently be maintained with one injection every 4 weeks. However, in view of the variations in individual response, careful supervision is required throughout treatment. Piportil L4 has actions similar to those of other phenothiazines. Among the different phenothiazine derivatives, Piportil L4 appears to be less sedating and to have a weak propensity for causing hypotension or potentiating the effects of CNS depressants and anesthetics. However, it produces a high incidence of extrapyramidal reactions.

Framycetin is a component of neomycin that is produced by Streptomyces fradiae. Framycetin is used for the treatment of bacterial eye infections such as conjunctivitis. Framycetin is an antibiotic. It is not active against fungi, viruses and most kinds of anaerobic bacteria. Framycetin works by binding to the bacterial 30S ribosomal subunit, causing misreading of t-RNA, leaving the bacterium unable to synthesize proteins vital to its growth. Framycetin is useful primarily in infections involving aerobic bacteria bacteria. Framycetin binds to specific 30S-subunit proteins and 16S rRNA, four nucleotides of 16S rRNA and a single amino acid of protein S12. This interferes with decoding site in the vicinity of nucleotide 1400 in 16S rRNA of 30S subunit. This region interacts with the wobble base in the anticodon of tRNA. This leads to interference with the initiation complex, misreading of mRNA so incorrect amino acids are inserted into the polypeptide leading to nonfunctional or toxic peptides and the breakup of polysomes into nonfunctional monosomes. Framycetin is a component of SOFRACORT (Framycetin sulphate - Gramicidin-dexamethasone), indicated for the treatment of blepharitis and infected eczema of the eyelid; allergic, infective and rosacea conjunctivitis; rosacea keratitis; scleritis and episcleritis; iridocyclitis, and other inflammatory conditions of the anterior segment of the eye, as well as otitis externa (acute and chronic) and other inflammatory and sebhorrheic conditions of the external ear.

Thevetin A is a steroidal (cardiac) glycoside that has been isolated from the seed kernels. Cardiotonic. It is a Na+-, K+-dependent adenosinetriphosphatase (Na+,K+-ATPase) inhibitor.

Ristocetin A is an antibiotic, derived from Nocardia lurida and exerts bactericidal effect against a range of Gram-positive cocci, Gramnegative diplococci, and Myco. tuberculosis. Ristocetin A and B were applied to treat staphylococcal infections but no longer used clinically because it caused thrombocytopenia and platelet agglutination. The Von Willebrand Ristocetin Cofactor [vWF:RCo] assay measures the ability of a patient’s plasma to agglutinate platelets in the presence of the antibiotic Ristocetin. The rate of Ristocetin induced agglutination is related to the concentration and functional activity of the plasma von Willebrand factor. Ristocetin is thought to bind to VWF at Glu1239-Pro-Gly Gly1242.

Aloin is a physiologically active anthraquinone present in aloe. It is a mixture of two diastereomers, termed aloin A (also called barbaloin) and aloin B (or isobarbaloin) which have similar chemical properties. Aloin B is used for research purposes and is not intended for diagnostic or therapeutic use.

Astragaloside A (Astragaloside IV) is the primary pure saponin isolated from Astragalus membranaceus, which has been widely used for the treatment of cardiovascular diseases. Astragaloside IV improves post-ischemic heart function and ameliorated reperfusion arrhythmias accompanied by a significant increase in myocardial antioxidative enzyme superoxide dismutase activity in rat hearts in vitro. While, Astragaloside IV's protective effect on heart function can be partially abrogated by the nitric oxide synthase inhibitor, Nomega-nitro-L-arginine methyl ester. Astrageloside IV has multiple pharmacologic effects, including anti-inflammatory, antifibrotic, antioxidative stress, anti-asthma, antidiabetes, immunoregulation, and cardioprotective effect via numerous signaling pathways. According to the existing studies and clinical practices, Astragaloside A possesses potential for broad application in many diseases.

Dexamethasone palmitate (a derivative of Dexamethasone), anti-inflammatory, antirheumatic, glucocorticoid receptor agonist, is reported as an ingredient of Limethason in Japan and Lipotalon in Germany. Limethason (Dexamethasone palmitate) inhibits the function of leukocytes and tissue macrophages. It restricts the migration of leukocytes in the area of inflammation. Limethason (Dexamethasone palmitate) decreases capillary permeability caused by histamine release. It inhibits the activity of fibroblasts and collagen formation. Limethason inhibits the activity of phospholipase A2, which leads to suppression of the synthesis of prostaglandins and leukotrienes. Limethason (Dexamethasone palmitate) is indicated for rheumatoid arthritis.

Quinine iodosulfate (herapathite) is a mixed salt of quinine and iodine. Its crystals are dichroic - they function as excellent linear light polarizers absorbing virtually all the light polarized along the shorter axis of the best-developed face. A sheet of quinine iodosulfate sandwiched between two glass plates is called polaroid. Polaroids find applications in areas such as automobile headlights and windscreens, hotel and aircraft windows and sunglasses.
