The synthesis and evaluation of gastroprotective effect of different tryptamine derivatives. Tryptamine derivatives have been synthesized by formation of amide or ester with some known anti oxidant molecules. These derivatives show excellent antioxidant property in vitro. Among all the derivatives the compound SEGA (3a), that was prepared by the combination of serotonin with gallic acid shows the greater antioxidant property than the other synthesized compounds both in vivo and in vitro. SEGA(3a) shows the gastroprotective effect against NSAIDs (indomethacin or diclofenac)-induced gastropathy in dose dependent manner and also accelerates the healing from injury. It prevents the NSAIDs-induced mitochondrial oxidative stress in vivo. This derivative prevents NSAID-induced mitochondrial oxidative stress-mediated apoptosis in vivo by preventing the activation of caspase 9 and caspase-3 and restores NSAIDs-mediated collapse of mitochondroial transmembrane potential and dehydrogenase activity. SEGA (3a) plays an important role as an iron chelator as well as intra mitochondrial ROS scavenger. Thus, SEGA (3a) is a potent antioxidant antiapototic molecule, which efficiently prevents NSAID-induced gastropathy and stress or alcohol-mediated gastric damage.

The present invention relates to compositions and methods for prophylactic and/or therapeutic treatment of conditions related to mitochondrial function. In various aspects, the present invention comprises administering one or more compounds selected from the group consisting of epicatechin, an epicatechin derivative, catechin, a catechin derivative, nicorandil, and a nicorandil derivative in an amount effective to stimulate mitochondrial function in cells. The methods and compositions described herein provide for reducing infarct size in the heart following permanent ischemia or ischemia /reperfusion (IR) event or method for delaying, attenuating or preventing adverse cardiac remodeling, and can assist in prevention of impaired mitochondria biogenesis and thus prevention of the consequences of impaired mitochondrial biogenesis in various diseases and conditions, as well as provide for the active therapy of mitochondrial depletion that may have already occurred.

The present invention relates to a cardiac targeting agent comprising tannic acid, which, by TANNylating a heart disease therapeutic agent to be delivered to the heart, provides the heart disease therapeutic agent with the ability to bind to the cardiac myocardium, thus enabling cardiac targeting and accumulation of the therapeutic agent, wherein the therapeutic agent can be targeted to the heart with high efficiency even via non-invasive intravenous administration alone, unlike conventional invasive methods used to target therapeutic agents to the heart.
