4-Aminobenzoic acid, also known as PABA, is a B vitamin derivative with UV absorption and antifibrotic properties. 4-Aminobenzoic acid can be generated by some intestinal bacteria, and acts as an intermediate in the synthesis of folate (vitamin B9). It is used in the treatment of fibrotic skin disorder, also can be used as a supplement for fatigue, irritability, depression, etc. Nutritional supplement in health care products.

A compound derived from the glycopeptide antibiotic, Vancomycin.

An impurity found in the macrolide antibiotic, Clarithromycin.

It is produced by the strain of Bacillus Polymyxa. Polymyxin B sulfate is a polypeptide antibiotic and is composed of polymyxins B1, B2, and B3 with fractions B1 and B2 comprising the majority of the mixture. Polymyxin B targets and alters permeability lipopolysaccharide (LPS) of gram-negative bacteria leading to lysing of the cell.

It is produced by the strain of Pseudomonas sp. Polymyxin B3 sulfate is an individual fraction found in the antibiotic mixture polymyxin B sulfate. Polymyxin B targets and alters permeability lipopolysaccharide (LPS) of gram-negative bacteria leading to lysing of the cell.

An impurity found in the macrolide antibiotic, Roxithromycin.

Dermicidin, also known as proteolysis-inducing factor (PIF), is a protein that in humans is encoded by the DCD gene. It is also an antimicrobial peptide (AMP) expressed in human sweat glands and is part of the human bodys innate immune defense.

A23187 Ca-Mg, the calcium-magnesium salt of A23187, has been found to be a Ca2+ ionophore and shows pro-inflammatory and allergic activities.

A diketopiperazine derivative isolated from Bacillus thuringiensis and Bacillus endophyticus. It is a secondary metabolite found in various marine fungi and bacteria. It is capable of activating N-acylhomoserine lactones (ahls), also capable of activating or antagonizing other luxr-based quorum-sensing systems.

It is a minor analogue of the zearalenone family of resorcinyl macrocyclic lactones produced by several species of fusarium. It exhibits estrogenic activity in animals and is a growth promotant for animals.

A degradation product of oxytetracycline, formed under acidic conditions. An initial dehydration to anhydrooxytetracycline then undergoes an internal cyclisation of the C5-OH to the C12 ketone. The resulting cleavage of the C12-C12a bond generates two isomers, α- and β-apooxytetracycline. alpha-Apooxytetracycline is an important standard for monitoring oxytetracycline stability.

3-Hydroxy palmitic acid methyl ester (3-hydroxy PAME) is an esterized long-chain fatty acid involved in quorum sensing in R. solanacearum, a bacteria that causes lethal wilting in plants.

Ustusol C is produced by the strain of Aspergillus ustus.

12-Hydroxy-6-epi-albrassitriol is produced from cultures of Aspergillus sp.

6,8-Di-O-methylcitreoisocoumarin is produced from Trichoderma sp. HPQJ-34.

Drechslerine A is a metabolite of the algicolous fungus Drechslera dematioidea.

Drechslerine D is a metabolite of the algicolous fungus Drechslera dematioidea.

F1839-I is produced from Stachybotrys sp.
