β-Apooxytetracycline is a potential impurity found in commercial preparations of oxytetracycline. β-Apooxytetracycline is a degradation product formed from oxytetracycline via acid hydrolysis. It has a relative potency of 0.1 compared with oxytetracycline for inhibiting the growth of aerobic sludge bacteria, an MIC50 value of 32 mg/L for tetracycline-sensitive strains of Pseudomonas, and MIC50 values of greater than 32 mg/L for tetracycline-sensitive strains of Agrobacterium, Moraxella, and Bacillus, as well as tetracycline-resistant strains of E. coli. β-Apooxytetracycline (10 mg/kg) is toxic to rats, decreasing body weight, disrupting blood cell counts, and inducing hepatocyte necrosis.

Arachidonic acid is metabolized in the vascular endothelium to epoxytrienoic acids (EETs or EpETrEs) by cytochrome P450 enzymes. The EETs are released in response to acetylcholine, bradykinin, arachidonic acid, or cyclic stretch. (±)14(15)-EET-SI is the methyl sulfonamide analog of 14(15)-EET. This substitution results in a metabolically more stable compound because it is not sensitive to β-oxidation or membrane esterification. (±)14(15)-EET-SI is equipotent to 14(15)-EET in vascular agonist activity as measured by relaxation of precontracted bovine coronary arteries. In addition, 14(15)-EET and the methyl sulfonamide analog both stimulate tyrosine phosphorylation and induce mitogenesis in renal epithelial cells.

The acyl amides are a family of endogenous lipids that act as potent modulators of pain and inflammation. The best characterized members of this family are the arachidonoyl amides, which includes N-arachidonoyl ethanolamide (AEA; anandamide). N-palmitoyl glycine (PalGly) contains an 18-carbon saturated fatty acid that is amide-linked to glycine and is structurally similar to the phospholipid-derived N-acyl ethanolamines. Endogenously produced in rat skin and spinal cord, PalGly is present in 100-fold greater amounts in skin and 3-fold greater in brain compared to AEA. Injection of 0.43 μg PalGly in rat hindpaw inhibits heat-induced firing of nociceptive neurons in rat dorsal horn. PalGly treatment induces transient calcium influx in native dorsal root ganglion (DRG) cells and in the PTX-sensitive, DRG-like cell line F-11 (EC50 = 5.5 μM).
