Limonoate D-ring-lactone

Limonoate a-ring-lactone

(1R,2R,2R,3S,5S,7R,10R,13S)-5-[(R)-(furan-3-yl)(hydroxy)methyl]-5,7,11,11-tetramethyl-8,15-dioxo-12,16-dioxaspiro[oxirane-2,6-tetracyclo[8.7.0.0¹,¹³.0²,⁷]heptadecane]-3-carboxylic acid

Limonoate a-ring-lactone is a member of the class of compounds known as limonoids. Limonoids are highly oxygenated, modified terpenoids with a prototypical structure either containing or derived from a precursor with a 4,4,8-trimethyl-17-furanylsteroid skeleton. All naturally occurring citrus limonoids contain a furan ring attached to the D-ring, at C-17, as well as oxygen containing functional groups at C-3, C-4, C-7, C-16 and C-17. Limonoate a-ring-lactone is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Limonoate a-ring-lactone can be found in lemon and sweet orange, which makes limonoate a-ring-lactone a potential biomarker for the consumption of these food products.

Vardenafil

1-(((3-(3,4-Dihydro-5-methyl)-4-oxo-7-propylimidazo(5,1-F)-as-triazin-2-yl)-4-ethoxyphenyl)sulfonyl)-4-ethylpiperazine

Vardenafil (Levitra) is an oral therapy for the treatment of erectile dysfunction. It is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). Penile erection is a hemodynamic process initiated by the relaxation of smooth muscle in the corpus cavernosum and its associated arterioles. During sexual stimulation, nitric oxide is released from nerve endings and endothelial cells in the corpus cavernosum. Nitric oxide activates the enzyme guanylate cyclase resulting in increased synthesis of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the corpus cavernosum. The cGMP in turn triggers smooth muscle relaxation, allowing increased blood flow into the penis, resulting in erection. The tissue concentration of cGMP is regulated by both the rates of synthesis and degradation via phosphodiesterases (PDEs). The most abundant PDE in the human corpus cavernosum is the cGMPspecific phosphodiesterase type 5 (PDE5); therefore, the inhibition of PDE5 enhances erectile function by increasing the amount of cGMP.
