10-F726006 - n-345-trimethoxyphenylpropionamide

TDN 345 is a catecholaminergic, blocker. It blocks the signal transduction pathway by inhibiting the neurotransmitter receptor and blocking the binding of neurotransmitters to their receptors. TDN 345 is administered orally, at doses ranging from 3 mg to 10 mg per day, to control levels of catecholamines in patients with carotid artery disease and cerebral vascular disease. TDN 345 has been shown to reduce the growth factor-mediated, cerebrovascular diseases. TDN 345 may also be useful in treating glioma and etidocaine-induced pain.

Impurity Pentoxifylline EP Impurity F
Applications Caffeine (Pentoxifylline EP Impurity F) is a bitter, white crystalline xanthine alkaloid that acts as a stimulant drug and a reversible acetylcholinesterase inhibitor (1,2,3). Caffeine is found in varying quantities in the seeds, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. In humans, caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness. Caffeine is a cardiac and respiratory stimulant; diuretic. Caffeine is toxic at sufficiently high doses. Caffeine is a non-competitive inhibitor of acetylcholinesterase (3).This compound is a contaminant of emerging concern (CECs).
