Pentoxifylline

Description

Pentoxifylline, also known as pentoxil or trental, belongs to the class of organic compounds known as xanthines. These are purine derivatives with a ketone group conjugated at carbons 2 and 6 of the purine moiety. Contraindications include intolerance to pentoxifylline or other xanthine derivatives, recent retinal or cerebral haemorrhage, and risk factors for haemorrhage. In addition, pentoxifylline improves red blood cell deformability (known as a haemorrheologic effect), reduces blood viscosity and decreases the potential for platelet aggregation and blood clot formation. Pentoxifylline is a drug which is used for the treatment of patients with intermittent lameness or immobility arising from chronic occlusive arterial disease of the limbs. There is some evidence that pentoxifylline can lower the levels of some biomarkers in non-alcoholic steatohepatitis but evidence is insufficient to determine if the drug is safe and effective for this use. However, pentoxifylline is also recommended for off-label use as an adjunct to compression bandaging for the treatment of chronic venous leg ulcers by the Scottish Intercollegiate Guidelines Network) (SIGN) as this has been shown to improve healing rates. Pentoxifylline, in combination with tocopherol and clodronate, has been found to heal refractory osteoradionecrosis of the jaw,and to be prophylactic against osteoradionecrosis. Like other methylated xanthine derivatives, pentoxifylline is a competitive nonselective phosphodiesterase inhibitor which raises intracellular cAMP, activates PKA, inhibits TNF and leukotriene synthesis, and reduces inflammation and innate immunity. Human studies have been conducted for Peyronie's disease. Pentoxifylline is an extremely weak basic (essentially neutral) compound (based on its pKa). This is its only FDA, MHRA and TGA-labelled indication. Pentoxifylline has also been shown to be of benefit in alcoholic hepatitis, with some studies demonstrating a reduction in risk of hepatorenal syndrome. In a Cochrane systematic review on the use of Pentoxifylline for intermittent claudication in 2015, the following was concluded "The quality of included studies was generally low, and very large variability between studies was noted in reported findings including duration of trials, doses of pentoxifylline and distances participants could walk at the start of trials. Most included studies did not report on randomisation techniques or how treatment allocation was concealed, did not provide adequate information to permit judgement of selective reporting and did not report blinding of outcome assessors. Given all these factors, the role of pentoxifylline in intermittent claudication remains uncertain, although this medication was generally well tolerated by participants". It is generic and sold under many brand names worldwide. Animal studies have been conducted exploring the use of pentoxifylline for erectile dysfunction and hearing loss.

Enzyme Details

5. Cytochrome P450 1A2

General function:: Involved in monooxygenase activity
Specific function:: Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It oxidizes a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Most active in catalyzing 2-hydroxylation. Caffeine is metabolized primarily by cytochrome CYP1A2 in the liver through an initial N3-demethylation. Also acts in the metabolism of aflatoxin B1 and acetaminophen. Participates in the bioactivation of carcinogenic aromatic and heterocyclic amines. Catalizes the N-hydroxylation of heterocyclic amines and the O-deethylation of phenacetin.
Gene Name:: CYP1A2
Uniprot ID:: P05177
Molecular weight:: 58406.915
