Acute myocardial effects of mitoxantrone in the rabbit
1987
Some clinical studies that were performed for the purpose of assessing the potential cardiotoxicity of mitoxantrone (DHAD) have shown that repeated administrations of the drugs in some patients cause a mild impairment of cardiac functions and morphological changes in the myocardial cells qualitatively similar to those elicited by anthracyclines. Since doxorubicin has been reported to cause acute cardiac effects, probably related to its chronic cardiotoxicity, experiments were carried out on the rabbit heart to investigate whether DHAD is also able to induce acute cardiac effects. Our results show that this drug caused a reversible dose-related impairment of cardiac contractility on the isol…
Design and synthesis of high affinity compounds for the Hsp60 expression control in carcinogenic processes
2013
First observed in cells exposed to high temperatures, Heat shock proteins (Hsps) are nowadays considered the most important cell “chaperone” complexes over-expressed in response to a number of cell stress stimuli.1 The chaperone activity is the main function of the eukaryotic Heat shock protein 60 kDa (Hsp60), involved in the capture and refold of unfolded or misfolded proteins. Additional roles in signal transduction,2 senescence activation3 and apoptosis4 have been ascribed to cytosolic Hsp60. During the carcinogenIc process, in vivo studies demonstrated increased levels of human Hsp60 in several organs, such as uterine exocervix,5 large bowel,6 and prostate.6 In this context, our study …
