	Product Abstract: Forskolin
		Furthermore, adenosine 3',5'-cyclic monophosphate contents were higher in the right ventricle and lower in the left ventricle from infarcted animals injected with saline, isoproterenol, or forskolin in comparison to the controls.
		Cyclic adenosine monophosphate formation was measured in cell membranes isolated from rhesus monkey ciliary muscle, ciliary muscle, ciliary processes, trabecular meshwork, and iris in the presence of forskolin, indomethacin, epinephrine, or indomethacin and epinephrine combined.
		This suggests that increased cyclic adenosine monophosphate content is not necessarily involved in the genesis of ischemia-induced arrhythmias, and that some other facet of adrenoceptor stimulation or catecholamine action may be involved.

		Adenosine is a naturally occurring, physiologically active molecule that is produced in many sites in the body in response to multiple types of stimuli (i.e.
		Adenosine mediates its varied effects by activating specific subtypes of adenosine receptors that are constituents of the cell membrane.
		However, the utility of adenosine as a therapeutic has been limited in that there is not a convenient way to selectively deliver adenosine to specific sites or to limit its ability activate untargeted adenosine receptor subtypes, that can produce undesired side effects or even antagonize the desired pharmacodynamic response.
