Zeatin is a cytokinin derived from adenine. Zeatin was discovered in immature corn kernels from the genus Zea. It promotes growth of lateral buds and when sprayed on meristems stimulates cell division to produce bushier plants.

trans-Zeatin ((E)-Zeatin) is the member of the plant growth hormone family known as cytokinins, which regulate cell division, development, and nutrient processing.

1,7-Dimethyluric acid is a metabolite of caffeine that serves as a biomarker for caffeine intake and can be detected in urine.

Adenosine (Standard) is a reference standard for adenosine, suitable for quantitative analysis, quality control, and biochemical experiments. Adenosine is a naturally occurring ribonucleoside composed of adenosine bound to ribose, exhibiting vasodilatory, antiarrhythmic, and analgesic effects.

7-Methylguanine is an orally available PARP1 inhibitor (Ki=61 μM) that competes with the substrate NAD+, exhibiting anticancer activity. As a natural nucleic acid metabolite, it may serve as a probe for protein-DNA interactions.

Inosine (Standard) is a reference standard for inosine, suitable for quantitative analysis, quality control, and biochemical experiments. Inosine is an endogenous purine nucleoside produced by the catabolism of adenosine. It acts as an agonist for adenosine receptors and can be used in studies of inflammation, immunity, and neuroprotection.
