methyl-xanthine

Pentoxifylline (PTX) modulates immunologic activity by stimulating cytokine production. Pentoxifylline is a methylxanthine derivative that inhibits phosphodiesterase and affects blood rheology. It also inhibits platelet aggregation and improves blood flow by increasing erythrocyte and leukocyte flexibility.

IBMX (Methylisobutylxanthine) is a broad-spectrum phosphodiesterase (PDE) inhibitor with inhibitory activity against PDE3, PDE4, and PDE5 (IC50=6.5/26.3/31.7 μM). IBMX enhances the intracellular cAMP level.

3-Methylxanthine, a xanthine derivative, is a cyclic guanosine monophosphate (GMP) inhibitor with an IC50 of 920 μM on guinea-pig isolated trachealis muscle. It inhibits xanthine crystallization and could protect patients with xanthinuria from developing renal xanthine calculi.

1-Methylxanthine is a caffeine derivative. 1-Methylxanthine is an essential human urinary metabolite of caffeine and theophylline (1,3-dimethylxanthine, TP). 1-Methylxanthine enhances the radiosensitivity of tumor cells.

1-Methylxanthine-[13C,D3] (Standard) is a reference standard of 1-Methylxanthine-[13C,D3] intended for quantitative analysis, quality control, and related biochemical research applications.

1-Methylxanthine-[13C4,15N3] (Standard) is a reference standard of 1-Methylxanthine-[13C4,15N3] intended for quantitative analysis, quality control, and related biochemical research applications.

1,7-Dibenzyl-3-methylxanthine belongs to Heterocyclic Compounds - Purines.

7-benzyl-3-methylxanthine belongs to Heterocyclic Compounds - Purines.

1,3-Dipropyl-7-methylxanthine is a reagent used in biochemical reactions.

8-methyl-xanthine is a useful organic compound for research related to life sciences and the catalog number is T131587.

Theophylline (1,3-Dimethylxanthine) is a methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac, and central nervous system stimulant activities. It inhibits the 3', 5'-cyclic nucleotide phosphodiesterase that degrades cyclic AMP, thus potentiating the actions of agents that act through adenylyl cyclases and cyclic AMP.

Theobromine (3,7-Dimethylxanthine), a xanthine alkaloid, is used as a bronchodilator and as a vasodilator.

Theophylline monohydrate (Quibron) appears to inhibit phosphodiesterase and prostaglandin production, regulate calcium flux and intracellular calcium distribution, and antagonize adenosine. Theophylline monohydrate is a natural alkaloid derivative of xanthine isolated from the plants Camellia sinensis and Coffea arabica. Physiologically, this agent relaxes the bronchial smooth muscle, produces vasodilation (except in cerebral vessels), stimulates the CNS, stimulates the cardiac muscle, induces diuresis, and increases gastric acid secretion; it may also suppress inflammation and improve contractility of the diaphragm.

1,9-Dimethylxanthine acts as an adenosine receptor antagonist, inhibiting the effects of adenosine on the central nervous system, thereby enhancing neural excitability. Utilized as a pharmacological tool in research, it aids in investigating physiological and pathological processes associated with adenosine.

8-Cyclopentyl-1,3-dimethylxanthine (CPT) is a potent antagonist of adenosine A1 receptor.

Paraxanthine (1,7-dimethylxanthine) is a metabolite of caffeine (sc-202514) which functions as an adenosine receptor ligand and a PARP-1 inhibitor in pulmonary epithelial cells. Studies suggest that Paraxanthine is structurally similar to caffeine and possibly mediates the physiological effects of caffeine. Also Paraxanthine acts as a competitive phosphodiesterase inhibitor, which increases intracellular cAMP, activates PKA, inhibits TNF-α and leukotriene synthesis. In addition, Paraxanthine acts as a Na+/K+ ATPase enzymatic effector.

ANA773 is a Toll-like Receptor 7 (TLR7) agonist prodrug with potential immunostimulating activity. Upon oral administration, ANA773 is metabolized into its active form that binds to and activates TLR7, thereby stimulating dendritic cells (DCs) and enhancing natural killer cell (NK) cytotoxicity. This activation results in the production of proinflammatory cytokines, including interferon alpha, and enhanced antibody-dependent cellular cytotoxicity (ADCC). TLR7 is a member of the TLR family, which plays a fundamental role in pathogen recognition and activation of innate immunity.

Paraxanthine-D6 is intended for use as an internal standard for the quantification of paraxanthine by GC- or LC-MS. Paraxanthine (T4973) is an active metabolite of caffeine. It is formed via N3-demethylation of caffeine by the cytochrome P450 (CYP) isoform CYP1A2. Paraxanthine (T4973) is an adenosine A1 and A2 receptor antagonist. In vivo, paraxanthine increases striatal cGMP and extracellular striatal dopamine levels and locomotor activity, as well as inhibits motor depression induced by the adenosine A1 agonist CPA or the adenosine A2 receptor agonist CGS 21680 in rats not habituated to caffeine. It also promotes wakefulness and increases locomotor activity and core temperature in narcoleptic transgenic mice without increasing behavioral anxiety.

1-(5-hydroxyhexyl)-3,7-dimethylxanthine-D6 is a deuterated compound of 1- (5-hydroxyhexyl)-3,7-dimethylxanthine (T21729).

1-3-carboxypropyl-3,7-dimethylxanthine-D6 is a deuterated compound of 1-[3-carboxypropyl]-3,7-dimethylxanthine.

1,7-Dimethylxanthine-[13C4,15N3] (Standard) is a reference standard of 1,7-Dimethylxanthine-[13C4,15N3] intended for quantitative analysis, quality control, and related biochemical research applications.

Paraxanthine-D6 (Standard) is a reference standard of Paraxanthine-D6 intended for quantitative analysis, quality control, and related biochemical research applications. Paraxanthine-d6 is used as an internal standard substance for the quantitative determination of Paraxanthine by gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-mass spectrometry (LC-MS). Paraxanthine is an active metabolite of caffeine.
