(R)-5-Oxopyrrolidine-2-carboxylic acid (D-Pyroglutamic acid) is a cyclic derivative of glutamic acid, physiologically present in mammalian tissues. It releases GABA from the cerebral cortex and exhibits anti-anxiety effects in a simple approach-avoidance conflict situation in rats. In clinical pharmacology experiments, it significantly shortens the plasma half-life of ethanol during acute intoxication.

(R)-pyrrolidine-2-carboxylic acid (D-Proline) is an isomer of the naturally occurring amino acid L-Proline. D-amino acids, including D-Proline, are found in relatively high abundance in human plasma and saliva, potentially originating from bacterial sources or endogenous production via amino acid racemase activity.

8alpha-(2-Methylacryloyloxy)-1-O-methylhirsutinolide 13-O-acetate is a natural product for research related to life sciences. The catalog number is TN3293 and the CAS number is 883872-71-7.

(R,E)-Deca-2-ene-4,6-diyne-1,8-diol is a natural from Toricellia angulata

(R)-(-)-2-Butanol, with catalog number T65765 and CAS number 14898-79-4, is a natural product used in life sciences research.

8alpha-(2-Methylacryloyloxy)hirsutinolide 13-O-acetate shows inhibitory activity toward CYP2A6 and MAO-A and MAO-B enzymes.

(R)-2-Isopropyl-8,8,8a-trimethyl-6,7,8,8a-tetrahydrophenanthrene-3,4-diol (compound 48), a catechol compound, is involved in the bioinspired synthesis of rearranged abietane diterpenes associated with pygmaeocins [1].

7-(6'R-hydroxy-3',7'-dimethylocta-2',7'-dienyloxy)coumarin is a natural product for research related to life sciences. The catalog number is TN6207 and the CAS number is 118584-19-3.

Gliovirin is a fungal metabolite that has been found inT. harzianumand has fungicidal, antimicrobial and anti-inflammatory activities.1It is active against the plant pathogenic fungusP. ultimum(MIC = 60 ng/ml) and the parasiteT. brucei brucei(IC50= 90 ng/ml), but has no effect on the plant pathogenic fungiR. solani,P. omnivorum,T. basicola,R. arrhizus, andV. dahliaeor the bacteriaB. thuringiensis,P. fluorescens, andX. malvacearumwhen used at concentrations up to 1,000 ng/ml.2,3Gliovirin decreases phorbol 12-myristate 13-acetate (TPA)- and ionomycin-induced increased expression of COX-2 (IC50= 1 μM) and protein levels of IL-2 in Jurkat cells (IC50= 5.2 μM).1 1.Rether, J., Serwe, A., Anke, T., et al.Inhibition of inducible tumor necrosis factor-α expression by the fungal epipolythiodiketopiperazine gliovirinBiol.
