Calcium Dibutyacyladenosine Cyclophosphate

Dibutyryladenosine cyclic 3',5'-monophosphate (DBACMP) is a mitochondrial function regulator that inhibits the synthesis of ATP by binding to the methyltransferase enzyme. DBACMP also has an inhibitory effect on other enzymes, such as dna binding activity and enzyme activities involved in cellular energy metabolism. DBACMP inhibits infectious diseases by altering signal pathways, which leads to the production of cytokines and chemokines that have pro-inflammatory effects and stimulate axonal growth. The drug may also bind to the atp-binding cassette transporter and inhibit mitochondrial calcium uptake. DBACMP binds to polymorphonuclear leucocytes and alters cytosolic calcium levels, which may lead to an increased production of protein genes for cell growth.

Bucladesine is a cyclic nucleotide derivative which mimics the action of endogenous cAMP and is capable of permeating the cell membrane. It has vasodilator properties and is used as a cardiac stimulant. Bucladesine is a phosphodiesterase inhibitor. Bucladesine is a cell permeable cAMP analog. The compound is used in a wide variety of research applications because it mimics cAMP and can induce normal physiological responses when added to cells in experimental conditions. cAMP is only able to elicit minimal responses in these situations. The neurite outgrowth instigated by bucladesine in cell cultures has been shown to be enhanced by nardosinone.
