Conditions:

Valeric acid is a colorless, oily liquid with an unpleasant odor. It is highly corrosive and must be handled with care. Valeric acid is mainly used as a chemical intermediate to manufacture flavors and perfumes, synthetic lubricants, agricultural chemicals, and pharmaceuticals. It is also used as a flavoring aid in foods. Valeric acid is considered safe as a food additive by the World Health Organization.

Strychnine is an indole alkaloid obtained from the seeds of the Indian tree Strychnos nux-vomica. It gets its scientific name “strychnos” from Carl Linnaeus, who classified it back in 1753, but it was known to the population of India way before then. Nux vomica originates in India. Strychnine-containing baits are currently labelled for below-ground use and are intended for the control of pocket gophers. Their use as indoor pesticides has been eliminated since 1989. In the past, strychnine has been used as a pesticide to control rats, moles, gophers, and coyotes. Strychnine is highly toxic to most domestic animals. Strychnine is a competitive antagonist at glycine receptors and thus a convulsant. It has been used as an analeptic, in the treatment of nonketotic hyperglycinemia and sleep apnea.

Thioctic acid also known as alpha-lipoic acid is a dietary supplement, which is a common ingredient in OTC (over-the-counter) multivitamin formulas and anti-aging supplements. Thioctic acid exists in both R- and S-enantiomeric forms, however, only R-form is essential as a cofactor in biological systems (the acid is coupled via an amide linkage to a lysine of several multienzyme complexes, such as the pyruvate dehydrogenase complex, the alpha-ketoglutarate dehydrogenase complex, the glycine cleavage system and the branched-chain oxo acid dehydrogenase complex). Most commercially available thioctic acid supplements are a mixture of both R and S enantiomers or R-form alone. Several studies have shown that the acid has beneficial effect on diabetes complications, cancer, glaucome, liver disease, etc. The mechanisms of thioctic acid is related to its antioxidant properties, metal chelator properties, however, those mechanisms need futher confirmation.

Targets:


Diflucortolone (used in the form of valerate prodrug) is a corticosteroid developed for the treatment of inflammatory skin diseases. It is supposed that Diflucortolone acts by inducing Annexin A1, a phospholipase A2 inhibitory protein, and thus controls the biosynthesis of prostagladins and leukotrienes. The drug is marketed as a cream under the tradename Nerisone.
Gentamicin C1 is a part of gentamicin C complex, containing gentamicin C1, gentamicin C1a, and gentamicin C2 which compose approximately 80% of gentamicin and have been found to have the highest antibacterial activity. Commercial gentamicin C is a mixture of gentamicin C1, C1a, and C2. Gentamicin C1 has a methyl group in the 6' position of the 2-amino-hexose ring and is N methylated at the same position. Gentamicin is a broad spectrum aminoglycoside antibiotic. Aminoglycosides work by binding to the bacterial 30S ribosomal subunit, causing misreading of t-RNA, leaving the bacterium unable to synthesize proteins vital to its growth. Aminoglycosides are useful primarily in infections involving aerobic, Gram-negative bacteria, such as Pseudomonas, Acinetobacter, and Enterobacter. In addition, some mycobacteria, including the bacteria that cause tuberculosis, are susceptible to aminoglycosides. Infections caused by Gram-positive bacteria can also be treated with aminoglycosides, but other types of antibiotics are more potent and less damaging to the host. In the past the aminoglycosides have been used in conjunction with penicillin-related antibiotics in streptococcal infections for their synergistic effects, particularly in endocarditis. Aminoglycosides are mostly ineffective against anaerobic bacteria, fungi and viruses. Aminoglycosides like gentamicin "irreversibly" bind to specific 30S-subunit proteins and 16S rRNA. Specifically gentamicin binds to 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. Gentamicin complex is used for treatment of serious infections caused by susceptible strains of the following microorganisms: P. aeruginosa, Proteus species (indole-positive and indole-negative), E. coli, Klebsiella-Enterobactor-Serratia species, Citrobacter species and Staphylococcus species (coagulase-positive and coagulase-negative).
