ABSTRACT:
Theobromine, formely known as xantheose is a bitter alkaloid of the cacao plant, with the chemical formula C7H8N4O2. It is found in chocolate, as well as in a number of other foods, including the leaves of tea plant, and the kola nut. Theophylline also known as 1,3-dimethylxanthine, is a methylxanthines drug used in therapy for respiratory diseases such as chronic obstructive pulmonary diseases (COPD) and asthma under a variety of brand name. Methylxanthine is also derivative of xanthenes. These all three are mostly present in tea, and these chemical have some effective property related with respiratory tract disorder.
KEYWORDS: Methylxanthine, Theobromine, theophylline, xanthose, immuno-modulatory action.
INTRODUCTION:
Theobromine, diuretics drugs and major alkaloidal constituent of cocoa. Theobromine is a xanthine alkaloid[7].
Therapeutics Uses of Theobromine:
1. Theobromine is associated with increases
in energy and urine production and the potential to shield heart health and
airways.[1]
2. In a study of 21 young adults with asthma,
theobromine capsule increases bronchial diameter, which increased airflow to
the lungs.[1}
3. It can reduce the levels of inflammatory
cytokines such as IFN-y and TNF-a.[1]
4. Human molars (teeth) were more protected
when treated with theobromine solution.[1]
5. In people with gout, crystals of uric acid
salts build up in the join which can trigger severe pain and inflammation. In
test tubes, theobromine prevented uric acid crystallization.[1]
6. Theobromine may cause blood pressure
to decrease by widening the blood vessels and stimulating urination.[1]
7. Theobromine extracted from cacao inhibits
the buildup of uric acid crystals, which may form kidney stones. Since
theobromine is a diuretics, it may also increasing urine flow.[1]
8. About 30mg theobromine supplements
contributed to staying asleep for a long period.[1]
9. Theobromine may raise HDL
(High-Cholesterol Level) is referred to as “good cholesterol”.[4]
10. In one study involving 24 healthy female subjects,
participants reported strong feeing of calmness after ingesting 700mg of
theobromine.[4]
General Introduction of Methylxanthines:
Methylxanthines are naturally occurring alkaloids in several foods and beverages all over the world as well as in some veterinary and human medications [8]. Methylxanthines are alkaloids that can be found in high concentration in tea, coffee and chocolate.[9]In comparison with theobromine caffeine has less effect on cardiac stimulation and coronary artery dilation[13].
Therapeutics Uses of Methylxanthines:
1. Methylxanthines, acting on adenosine
receptors in the central nervous system, enhance arousal mood and concentration
levels.[2]
2. The main pharmacological effects of
methylxanthines include central nervous system stimulation, diuresis, cardiovascular
and metabolic effects, bronchial relaxation and increased secretion of gastric
acids.[2]
3. Methylxanthines relax airways and vascular
smooth muscle and as mentioned earlier, a relationship can be observed between
PDE inhibition by methylxanthine and relaxation of airways smooth muscles.[3]
4. Methylxanthines have vasodilatory,
Anti-inflammatory and immunomodulatory actions[11].
5. The potential effects of methylxanthine
are numerous, controversial and of uncertain importance[11].
6. Methylxanthines increases chemo-receptor
sensitivity as well as respiratory drive and can also improve diaphragmatic
contractility[12].
7. Skeletal muscles are stimulated more by
caffeine than by other methylxanthines[12].
General Introduction of Theophylline:
Theophylline is a naturally occurring occuring alkaloid
closely related to caffeine. The pharmacologic actions of theophylline include
stimulation of respiration, augmentation of cardiac inotropy and chronotropy,
relaxation of smooth muscle including that in te bronchi and the blood vessels
and other than cerebral vessels and diuresis.[6]
Therapeutics
Uses of Theophylline:
1. Theophylline is widely prescribed drugs
for the treatment of asthma and chronic obstructive pulmonary diseases (COPD).[5]
2. It was also used as diuretics.[5]
3. Theophylline increases the activity and
number of suppressor T-cells and reduces the activity of many inflammatory
cells implicated in asthma[10].
4. For IV administration aminophylline
(Containing 85% anhydrous theophylline by weight) is used because of its
greater aqueous solubility[10].
5. Theophylline increases the forces and rate
contraction of cardiac muscle through it’s effect on CAMP, but also causes
arterial vasodilation by inhibiting the breakdown of CGMP[11].
6. Theophylline is a potent antagonist at
adenosine A1, A2 and A3 receptors and may reduce
broncho-constriction by this mechanism[11].
7. The action of theophylline on HDAC may
potentiate the anti-inflammatory effects of costicosteroids[11].
