Pentoxifylline

3,7-dimethyl-1-(5-oxohexyl)-2,3,6,7-tetrahydro-1H-purine-2,6-dione

C13H18N4O3 (278.1378838)

Pentoxifylline is only found in individuals that have used or taken this drug. It is a methylxanthine derivative that inhibits phosphodiesterase and affects blood rheology. It improves blood flow by increasing erythrocyte and leukocyte flexibility. It also inhibits platelet aggregation. Pentoxifylline modulates immunologic activity by stimulating cytokine production. [PubChem]Pentoxifylline inhibits erythrocyte phosphodiesterase, resulting in an increase in erythrocyte cAMP activity. Subsequently, the erythrocyte membrane becomes more resistant to deformity. Along with erythrocyte activity, pentoxifylline also decreases blood viscosity by reducing plasma fibrinogen concentrations and increasing fibrinolytic activity. It is also a non selective adenosine receptor antagonist.

Pantetheine

2,4-dihydroxy-3,3-dimethyl-N-{2-[(2-sulfanylethyl)carbamoyl]ethyl}butanamide

C11H22N2O4S (278.1300212)

Pantetheine is the mercaptoethyl conjugated amide analogue of pantothenic acid (Vitamin B5). The dimer of this compound, pantethine is more commonly known, and is considered to be a more potent form of vitamin B5 than pantothenic acid. Pantetheine is an intermediate in the production of Coenzyme A by the body. An intermediate in the pathway of coenzyme A formation in mammalian liver and some microorganisms.
