Natural and synthetic methylxanthines inhibit insect feeding and are pesticidal at concentrations known to occur in plants. These effects are due primarily to inhibition of phosphodiesterase activity and to an increase in intracellular cyclic adenosine monophosphate. At lower concentrations, methylxanthines are potent synergists of other pesticides known to activate adenylate cyclase in insects. These data suggest that methylxanthines may function as natural insecticides and that… Expand
Benzoate adjuvant to increase the utility of methylxanthine pesticides: identification of a potential rodenticide formulation for organic food production
There is growing interest in the use of natural products such as caffeine and theobromine for control of a variety of pest species. We hypothesized that the limited water solubility of theseExpand
Nicotine and Other Insecticidal Alkaloids
TLDR
It is now generally believed that the ecological role of these compounds, often acting in concert with other nonalkaloidal substances, is to provide a chemical defense against predators and pathogens in a sustained manner through multiple biological mechanisms. Expand
Potential metabolic mutagens of caffeine and various methylxanthines.
TLDR
Evaluation of these compounds against Salmonella typhimurium, strain TA100, has demonstrated that, in contrast to caffeine, 7-hydroxymethyltheophylline and the 3,7-bis(hydroxyl)-1-methylxanthine mixture did exhibit cytotoxicity. Expand
Distribution and biosynthesis of caffeine in plants.
TLDR
The present review begins by summarizing the distribution of methylxanthines and methyluric acids in the plant kingdom, and then provides an up-to-date account of the biosynthesis of purine alkaloids. Expand
Synthesis and biological activities of novel methyl xanthine derivatives
Caffeine is one of methyl xanthine compounds, which has the similar mode of action as ryanodine receptor insecticide. In order to find novel and efficient insecticide, structural modification ofExpand
The Medicinal Chemistry of Caffeine.
TLDR
The diversity of caffeine's molecular activities on receptors and enzymes indicates a complex interplay of several mechanisms contributing to neuroprotective effects and highlights new targets as attractive subjects for drug discovery. Expand
Xanthine Alkaloids: Occurrence, Biosynthesis, and Function in Plants.
TLDR
The in planta role of caffeine in chemical defense that has been demonstrated using transgenic caffeine-forming tobacco and chrysanthemum plants, which are resistant to attack by pathogens and herbivores are considered. Expand
Bacterial Degradation of Caffeine: A Review
TLDR
Evidence has proved the harmful effects of caffeine thus opening a path in the field of caffeine biodegradation, which provides a safe and cheaper alternative compared to chemical and physical methods. Expand
Caffeine, a naturally occurring acaricide.
TLDR
It is demonstrated that caffeine inhibits mite growth and allergen production and is not detected in the food media or caffeine. Expand
Transgenic tobacco plants producing caffeine: a potential new strategy for insect pest control
TLDR
The recent results suggest a novel approach to strengthen anti-herbivore traits by producing caffeine in crop plants by using recombinant enzymes that yielded caffeine in in vitro reconstitution experiments. Expand

N-demethylchlordimeform: a potent partial agonist of octopamine-sensitive adenylate cyclase.
TLDR
Results indicate that, at low concentrations, DCDM can bind specifically and reversibly toOctopamine receptors with a resultant activation of adenylate cyclase, and CDM, on the other hand, has little direct effect on the octopamine receptor. Expand
Methyl xanthine phosphodiesterase inhibitors behave as prostaglandin antagonists in a perfused rat mesenteric artery preparation.
TLDR
MIX inhibited effects of PGF2alpha on rat uterus and PGE1 on guinea pig ileum, and effective concentrations of theophylline were similar to the therapeutic levels in human plasma, suggesting that PGs may also be involved in regulating PDE action. Expand
Mechanism of methylxanthine sensitization of norepinephrine responses in a coronaryartery.
TLDR
It is concluded that the methylxanthinesenhance beta-adrenergic receptor-mediated responses via a blockade of catecholamine uptake, giving rise to an increased concentration of agonist at receptors, and not by an action linked to cyclic AMP accumulation, consequent to receptor activation. Expand

TLDR
After pretreatment of rat brain synaptic membranes with adenosine deaminase to remove endogenousAdenosine, 2-chloro[3H]adenosine binds to two sites with Kd values of 1.3 and 16 nM and corresponding Bmax values of 207 and 380 fmol/mg of protein. Expand
Adenosine 3',5'-phosphate in biological materials. I. Purification and properties of cyclic 3',5'-nucleotide phosphodiesterase and use of this enzyme to characterize adenosine 3',5'-phosphate in human urine.
TLDR
Data indicated a significant role for the enzyme in the control of the levels of adenosine 3’,5’-phosphate present in biological systems, which was very desirable because of the extremely low levels present in most biological materials. Expand
An isotopic assay of cyclic 3',5'-nucleotide phosphodiesterase with aluminum oxide columns.
TLDR
The method was shown to be applicable in the isotopic assay of cyclic 3′,5′-nucleotide phosphodiesterase activity over a broad range of substrate concentrations and its possible use in a simultaneous cyclase-phosphodiesterases assay is described. Expand
OCTOPAMINE: A HIGH‐AFFINITY UPTAKE MECHANISM IN THE NERVOUS SYSTEM OF THE COCKROACH
  • P. Evans

TLDR
The significance of the high‐affinity uptake component is discussed in terms of amine inactivation, and its parallels with noradrenaline uptake in the vertebrate nervous system are considered. Expand
Influence of Caffeine and other Methylxanthines on Mechanical Properties of Isolated Mammalian Heart Muscle: EVIDENCE FOR A DUAL MECHANISM OF ACTION
TLDR
The results suggest that the methylxanthines exert two effects on excitation-contraction coupling, one of these is presumed to be the inhibition of calcium sequestration by the sarcoplasmic reticulum; the other may be an effect on the cell membrane that leads to increased calcium entry. Expand
Adenosine-elicited accumulation of cyclic AMP in brain slices: potentiation by agents which inhibit uptake of adenosine.
TLDR
The results are compatible with the hypothesis that the specific inhibition of uptake ofadenosine potentiates adenosine or amine-elicited accumulations of cyclic AMP by increasing the effective extracellular concentration of adenoine within the slice. Expand
Calcium requirement for the inhibition by theophylline of histamine release from mast cells.
TLDR
The results suggest that Ca2+ is required in the interaction of theophylline and specific sites on mast cells or in the mast cell response to theophyLLine which probably does not involve the cyclic AMP increase and is linked to the inhibition of histamine release. Expand
