- the water solubility of the test molecules prepared in Example 4, 5 and 6 were evaluated and the corresponding results at 35-40° C. are as follows:
- test molecule consisting of chemically complexed Garcinol with cyclodextrin is highly water soluble. Hence the test molecule has increased water solubility and higher in-vivo bioavailability when compared to Garcinol.

- SR sarcoplasmic reticulum
- Garcinol protects cardiomyocytes from Doxorubicin induced cardiac dysfunction.
- Doxorubicin is a chemotherapy drug which induces impaired Ca 2+ handling in Sarcoplasmin Reticulum resulting in reduced cardiac function.

- GSH glutathione
- the therapeutic potential of the test molecule at a dose of 20 mg/kg is comparable to that of administration of 100 mg/kg (p.o.) of Garcinol as seen in Example 9. This confirms that the chemical complexing of Garcinol with Cyclodextrin increases its therapeutic index by making it more efficacious. Moreover, this activity of the test molecule was achieved without any mortality of the animals indicating elimination of toxicity. Hence, the above examples demonstrate a significant enhancement of therapeutic characteristics of the test molecule in treating cardiac dysfunction induced by Doxorubicin.
- mice Male Wistar rats were pretreated with 20 mg/kg (p.o.) of test molecule for 30 days. On days 1, 7, 14, 21 and 28, Doxorubicin at a dose of 3 mg/kg (i.p.) was administered intravenously. On Day 30, animals were sacrificed for histopathological examination of the heart.
- test molecule significantly normalized prolongation of QT, ST and QTc intervals induced by Doxorubicin and prevented reduction in heart rate. Improvement was observed in mean arterial blood pressure, systolic and diastolic blood pressures. Reduction in oxidative stress was evident from increased GSH level and decreased lipid peroxidation in comparison with Doxorubicin control group. Protection against Doxorubicin induced myocardial injury was seen in histopathological examination of the heart. The test molecule significantly reduced Myocardial Necrosis, Inflammation, Cytoplasmic Vacuoles, Cytoplasmic Eosinophilia, and Vascular Congestion.
- test molecule can be effectively used in combination with Doxorubicin for effectively minimizing the cardiotoxic side effects and enabling increased dosage and treatment regimen of the chemotherapy.
- Digitalis is used in treatment of atrial fibrillation, flutter and congestive heart failure. It has dose dependent toxicity limitation. At high doses, Digitalis induces irregular heartbeat, ectopic atrial tachycardia and cardiac arrest. This study was conducted to evaluate the potential protective activity of test molecule against Digitalis induced cardiac dysfunction, thereby enabling increase in dosage of Digitalis.
- test molecule significantly increased the dose of Digitalis required to produce ectopic beat, atrial fibrillation, and cardiac arrest.
- Test molecule also reduced Digitalis induced oxidative stress as seen from increased GSH level and decreased Lipid Peroxidation when compared to Digitalis control group. Histopathological examination revealed that test molecule significantly reduced Myocardial Necrosis, Inflammation, Cytoplasmic Vacuoles, Cytoplasmic Eosinophilia, and Vascular Congestion, thereby protecting myocardial tissue against Digitalis induced cardiac dysfunction.
- test molecule protects from Digitalis induced cardiac dysfunction.
- test molecule will enable increase in the dose of Digitalis used in treatment thereby enhancing its therapeutic effects.
- test molecule against Isoproterenol induced cardiac dysfunction was evaluated as follows.
- Isoproterenol Male Wistar rats were pretreated with 20 mg/kg (p.o.) of test molecule 18 days. From Day 9, Isoproterenol at a dose of 1 mg/kg/day was administered intravenously for 10 days. Isoproterenol administration induced significant changes to the QT and ST interval. Isoproterenol induced oxidative stress was observed by decreased Glutathione (GSH) and increased lipid peroxidation concentrations in the heart.
- Glutathione Glutathione
- test molecule protects the heart from Isoproterenol induced cardiac dysfunction. Hence, when used in combination with Isoproterenol the test molecule increases the therapeutic potential of Isoproterenol.
- Aortic banding creates a pressure overload on the heart by narrowing the aorta.
- Takizawa et. al. (1999) has reported that under conditions of pressure-overload there is a reduction in transcription of SERCA2 mRNA expression which decreases SERCA2 protein concentration and in turn decreases Ca 2+ uptake in the SR.
- This result in reduced cardiac function characterised by an initial increase in blood pressure indicating compensating mechanism of the heart to pump more blood, followed by a fall in the blood pressure and finally causing congestive heart failure.
- the effect of the test molecule is protecting the heart from congestive heart failure was evaluated in this experiment.
- test molecule significantly prevented reduction in heart rate induced by aortic stenosis and normalized QT, ST and QTc intervals. Improvements were observed in mean arterial blood pressure, systolic and diastolic blood pressures. The test molecule significantly reduced aortic stenosis induced cardiac dysfunction as measured by heart weight to body weight ratio and left ventricular weight to body weight ratio. Reduction in oxidative stress was also observed.
- Aortic stenosis model represents a condition of cardiac dysfunction caused by increased peripheral resistance leading to pressure overload. This condition can be induced by other physiological disease conditions like hypertension, atherosclerosis, myocardial infarction, ischemic heart disease and cardiomyopathy. Hence the above experiment shows that the test molecule will be effective in the treatment and management of cardiac dysfunction induced by pressure overload.
