Abstract
Conjugation drug therapy of melatonin has emerged as a promising
modality for reducing cisplatin (cis-diammine di chloro platinum
(II) or cis-DDP or CDDP) induced toxicity. The objective of the
present study is to determine the attenuation of cisplatin induced
toxicity by Melatonin loaded on a Dextran modified Iron Oxide
nanoparticles (DIO-M). The DIO-M was developed, characterized
and analyzed. Loading of melatonin was confirmed by Fouriertransform
infrared spectroscopy (FTIR). Particle size analysis was
carried out using Dynamic Light Scattering (DLS) and Transmission
Electron Microcope (TEM) techniques. Phase purity of crystals was
determined by X-ray diffraction analysis (XRD) and the magnetic
property of particle material was characterized by Vibrational
sample magnetometry (VSM). Cytotoxicity studies using by MTT
assay in L929 cell lines confirmed the melatonin nanoparticles to be
nontoxic. The protective effect of DIO-M against cisplatin induced
toxicity was confirmed by antioxidant parameters such as reduced
glutathione, superoxide dismutase, and glutathione peroxidase and
glutathione reductase. Free radical mediated cell damage was
quantitatively determined by the measurement of malondialdehyde
level. It was found that the inhibitory effect of malondialdehyde
levels by DIO-M could be attributed to the increased activities
of antioxidant enzymes (p<0.005). Splenocyte proliferation
demonstrated that DIO-M has the ability to influence the spleen
cells. Splenocytes when treated with cisplantin and DIO-M was able
to overcome the antiproliferative property of cisplatin. Hence, these
findings contribute with important insight that DIO-M can be useful
for management of toxicity induced by anti-cancer drug cisplatin.
