Thromboxane A2, as an unstable intermediate between the prostaglandin endoperoxides and thromboxane B2, is a potent inducer of platelet aggregation and causes vasoconstriction.

16,16-dimethyl PGA2 is a metabolism-resistant analog of PGA2 with a prolonged in vivo half-life. It inhibits the proliferation of Sendai virus in cultured African green monkey kidney cells by >90% at a concentration of 4 μg/ml. Daily infusion of 10 μg of 16,16-dimethyl PGA2 methyl ester into mice infected with influenza A virus increased survival by 40%. Similar treatment of mice inoculated with erythroleukemia cells delayed tumor growth and increased survival time.

8-iso Prostaglandin A2 是一种异前列腺素，可由花生四烯酸的非酶氧化产生。

15(R)-Pinane thromboxane A2 is the (R)-epimer of pinane thromboxane A2 . 15(R)-PTA2 does not inhibit collagen-induced platelet aggregation (IC50s = 120-130 μM). It does not affect gastric tone in isolated rat gastric fundus when used at concentrations of 0.5 or 1.5 μg/ml and is less effective than PTA2 at inhibiting prostaglandin-induced contraction of isolated rat stomach muscle.

PGA2 is a naturally occurring prostaglandin in gorgonian corals where it may function in self defense. It is generally not present in mammals. PGA2 has low biological potency in most bioassays, but it does show some antiviral/antitumor activity.[1] At a 25 uM concentration, PGA2 blocks the cell cycle progression of NIH 3T3 cells at the G1 and G2/M phase .[2] It has also been shown to act as a vasodilator with natriuretic properties.[3]

Chromomycin A2 is an aureolic acid that has been found in several marine actinomycetes and has antibacterial and anticancer activities. Chromomycin A2 inhibits the growth of B. subtilis in an agar diffusion assay. It also inhibits the growth of human SGC7901 gastric cancer, HepG2 hepatocellular carcinoma, A549 lung epithelial adenocarcinoma, HCT116 colon cancer, and COC1 ovarian cancer cells, as well as human umbilical vein endothelial cells (HUVECs; IC50s = 4, 0.5, 3, 5, 5, and 8 nM, respectively). Chromomycin A2 (30 nM) halts the cell cycle in the G0/G1 phase and increases the protein levels of LC3A and LC3B in MALME-3M melanoma cells, indicating that it induces autophagy. It also increases the levels and promoter activity of the autophagic proteins ATG7 and ATG10 and reduces cell viability to 50% in human SCC-11 squamous cell carcinoma cells when used at a concentration of 30 nM.

Golgicide A-2 (GCA-2), a derivative of Golgicide A (GCA), is the highly active enantiomer of GCA. It exhibits exceptional selectivity and efficiency in eradicating An. stephensi larvae, thus making it a valuable tool for researching dengue virus-related diseases.
