Aflatoxin G1-13C17is intended for use as an internal standard for the quantification of aflatoxin G1by GC- or LC-MS. Aflatoxin G1is a mycotoxin that has been found inA. terricola.1In vivo, aflatoxin G1is lethal to ducklings (LD50= 1.18 mg kg).2It induces hepatocellular carcinoma tumor formation and lethality in rats when administered at doses of 1.4 and 3 mg animal, respectively. Aflatoxin G1also inhibits liver and kidney succinate dehydrogenase and fumarase, as well as kidney cytochrome oxidase, NADH oxidase, α-glycerophosphate dehydrogenase, isocitrate dehydrogenase, and malate dehydrogenase in rats.3 1.Moubasher, A.H., el-Kady, I.A., and Shoriet, A.Toxigenic Aspergilli isolated from different sources in EgyptAnn.

Thromboxane B2 (TXB2) is released in substantial quantities from aggregating platelets and metabolized during circulation to 11-dehydro TXB2 and 2,3-dinor TXB2. In rats and rabbits, 2,3-dinor TXB1 has been identified as another urinary metabolite of TXB2. However in human urine, only trace amounts of 2,3-dinor TXB1 have been identified. In rats, 2,3-dinor TXB1 is excreted at a much higher rate than 2,3-dinor TXB2 (19.2 ± 4.9 ng/24 hr and 1.6 ± 0.3 ng/24 hr, respectively). Therefore, urinary 2,3-dinor TXB1 is a suitable marker of thromboxane biosynthesis in rats.

4'-Acetyl chrysomycin A is a bacterial metabolite and derivative of chrysomycin A that has been found inStreptomycesand has antibacterial and anticancer activities.1It is active against strains of methicillin-resistantS. aureus(MRSA) and vancomycin-resistant strains ofE. faecalisandE. faecium(MICs = 0.5-2 μg/ml for all). 4'-Acetyl chrysomycin A is cytotoxic against a panel of human cancer cell lines, including doxorubicin-sensitive or -resistant cells (IC50s = 0.085-0.26 and 3.4-16 ng/ml, respectively). 1.Wada, S.-I., Sawa, R., Iwanami, F., et al.Structures and biological activities of novel 4'-acetylated analogs of chrysomycins A and BJ.

The mating and social behaviors of insects are largely orchestrated by a suite of volatile cuticular hydrocarbon pheromones. 7(Z),11(Z)-Heptacosadiene is the predominant female-specific courtship pheromone of the fruit fly D. melanogaster. At amounts above 100 ng, 7(Z),11(Z)-heptacosadiene elicits wing vibrations in male D. melanogaster flies in a dose-dependent manner.

Thromboxane B2 (TXB2) is a compound significantly released from aggregating platelets and undergoes metabolic transformation during circulation into 11-dehydro TXB2 and 2,3-dinor TXB2. The latter, 2,3-dinor TXB2, serves as a prevalent urinary metabolite of TXB2 and acts as an indicator for in vivo TXA2 synthesis. Studies have shown that in healthy male volunteers, the median excretion rate of 2,3-dinor TXB2 is measured at 10.3 ng hour, equivalent to 138 pg mg of creatinine.
