애플리케이션
Caffeine has been used as a radiosensitizing agent utilized for studying its impact in inhibiting the catalytic activity of ATM and ATR Kinase.[1] CTGF is an important modulator protein of fibrogenic TGF-β. Hence, this product has also been used for examining the caffeine-dependent regulation of CTGF expression in rat hepatocytes.[2]
생화학적/생리학적 작용
Caffeine is a central nervous system stimulant, adenosine receptor antagonist as well as adenosine 3′,5′-cyclic monophosphate (cAMP) phosphodiesterase inhibitor. It stimulates the sarcoplasmic reticulum (SR) Ca2+-release channel which facilitates the excitation-contraction coupling in cardiac muscle.[3] It has also been reported to affect cellular calcium levels, releasing calcium from intracellular stores. Caffeine overrides the cell cycle effects of various chemicals such as protease inhibitors, preventing apoptosis; and it has been shown to inhibit cellular DNA repair mechanisms.[4]

Static in vitro permeation experiments are commonly used to gain insights into the permeation properties of drug substances but exhibit limitations due to missing physiologic cell stimuli. Thus, fluidic systems integrating stimuli, such as physicochemical fluxes, have been developed. However

Caffeine potentiates the mutagenic and lethal effects of genotoxic agents. It is thought that this is due, at least in some organisms, to inhibition of DNA repair. However, direct evidence for inhibition of repair enzymes has been lacking. Using purified

Caffeine exposure sensitizes tumor cells to ionizing radiation and other genotoxic agents. The radiosensitizing effects of caffeine are associated with the disruption of multiple DNA damage-responsive cell cycle checkpoints. The similarity of these checkpoint defects to those seen in ataxia-telangiectasia

Caffeine is thought to affect excitation-contraction coupling in cardiac muscle by activating the sarcoplasmic reticulum (SR) Ca2+-release channel. The effect of caffeine at the single channel level was studied by incorporating canine cardiac SR vesicles into planar lipid bilayers. Cardiac
