Lexithromycin is an early semi-synthetic erythromycin, prepared by reaction of the 9-keto moiety to methyl oxime. Lexithromycin has improved absorption in vivo over erythromycin due to increased hydrophopicity and pH stability. Like all erythromycins, lexithromycin shows broad spectrum antibacterial activity and acts by binding to the 30S and 50S ribosomal sub-units, blocking protein synthesis. Formulations containing lexithromycin were tested in clinical trials as treatment for HIV but were discontinued.

Conditions:

Gluceptate sodium also known as sodium glucoheptonate (H-Quest A300) is a non-toxic, a non-hazardous chelating agent, which forms stable complexes with di- and trivalent metal ions such as Ca2+, Fe2+, Fe3+, Al3+, etc. This substance is highly compatible with strong alkaline mediums and can prevent the bacterial degradation of the solution. Gluceptate sodium has various applications in water treatment, agricultural, cosmetics, textile processing and in some others fields.

Conditions:

D-aspartic acid is an essential amino acid and a key ingredient in various testosterone boosting anti-estrogen supplements. D-aspartic acid is not used to build proteins; instead, it plays a role in making and releasing hormones in the body. It is an endogenous NMDA receptor agonist with similar activity to the L-isomer. D-aspartic acid also enhances the release of luteinizing hormone (LH) and testosterone. This action is mediated in the pituitary by cGMP and in the testis by cAMP, which acts as the second messengers in the signal transduction in the pituitary and testes respectively. The pituitary and testis possess a D-Aspartate racemase, which provides the necessary production of this isomer.

Berythromycin or erythromycin B (also known as 12-deoxyerythromycin A), an acid-stable co-metabolite of the antibiotic erythromycin A, exhibits broad-spectrum antibiotic activity. The antibacterial activity of erythromycin B is similar to that of erythromycin A, but after acid-treatment, resembling exposure to the stomach, erythromycin B substantially retains antibacterial activity, whereas erythromycin A does not. Erythromycin B played an integral part of the structure activity relationship studies of semi-synthetic erythromycins.
