Methylxanthines activate histone deacetylases, promoting the deacetylation of histone and subsequent DNA folding. This inhibits the synthesis of pro-inflammatory factors that induce asthma attacks and exacerbations, achieving anti-inflammatory effects. [19] For asthma maintenance therapy, methylxanthines are taken orally. [2]
An interesting off-label indication of pentoxifylline is the supportive treatment of distal diabetic neuropathy, where it can be added, for example, to thioctic acid or gabapentin. [17] Theoretically, it can (among other things) act prophylactically against ulcerative changes of the lower limbs associated with chronically decompensated diabetes.
IBMX (3-isobutyl-1-methylxanthine), like other methylxanthine derivatives, is both a: . competitive non-selective phosphodiesterase inhibitor [1] which raises intracellular cAMP, activates PKA, inhibits TNFα [2] [3] and leukotriene [4] synthesis, and reduces inflammation and innate immunity, [4] and
anti-inflammatory effects; central nervous system stimulatory effect, mainly on the medullary respiratory center [4] [5] The main therapeutic uses of theophylline are for treating: [2] Chronic obstructive pulmonary disease (COPD) [6] Asthma; infant apnea [7]
Xanthine (/ ˈ z æ n θ iː n / or / ˈ z æ n θ aɪ n /, from Ancient Greek ξανθός xanthós ' yellow ' for its yellowish-white appearance; archaically xanthic acid; systematic name 3,7-dihydropurine-2,6-dione) is a purine base found in most human body tissues and fluids, as well as in other organisms.

7-Methylxanthine (7-MX), also known as heteroxanthine, is an active metabolite of caffeine (1,3,7-trimethylxanthine) and theobromine (3,7-dimethylxanthine). [ 1 ] [ 2 ] It is a non-selective antagonist of the adenosine receptors .
Methylxanthines are chemical compounds which are derivatives of xanthine with one or more methyl groups, including: One methyl group: 1-Methylxanthine;
A long, thin red area may be seen as the inflammation follows a superficial vein. This area may feel hard, warm, and tender. The skin around the vein may be itchy and swollen. The area may begin to throb or burn. Symptoms may be worse when the leg is lowered, especially when first getting out of bed in the morning. A low-grade fever may occur.
