2 Oxygen metabolism of the cells produces free radical which starts chain reaction and finally damages the cells. It may cause the mutagenesis and carcinogenesis and

forms a tumor. The mitochondrial and cytolytic enzyme activity functions to prevent the oxidation of the cells and to develop the biotransformation Entinostat ic50 and detoxification. In the cancer states all the hematological parameters, serum parameters, plasma sodium, potassium, magnesium and calcium levels, and glycolytic and non-glycolytic enzyme levels get changed. It may cause some physiological dysfunctions. Most of the cancer drugs are highly toxic and having serious side effects. So nowadays novel chemo preventive drugs are developed to overcome these severe side effects. Quinazolinone derivatives having a different pharmacophore group each having different

modes of action for the treatment of cancer. Several quinazoline derivatives are reported for cancer treatment especially in breast cancer.3 Breast cancer is the second death causing disorder and the treatment causes savior adverse effect, so the present study was aimed to develop simple and novel N-aryl-4-chloro quinazolinone urea derivatives against mammary carcinoma with lesser side effect. Serious of N-aryl-4-chloro quinazolinone urea derivatives (1-(7-chloro-2-(4-chloro-phenyl)-3-N-aryl-quinazoline)-4-one urea) are prepared by the reaction of Wohler’s classical synthesis followed BMS-354825 by condensation reaction4 (Scheme 1). The melting point was recorded. The purity of the compound was checked by precoated silica gel 60 F254 TLC plate (E. Merck) as an adsorbent and the mobile phase was ethyl acetate:n-butanol:water (6:3:1), IR spectrum was recorded by using KBR pellets (Shimadzu-8400S FTIR). Proton NMR was recorded by using APACT Fourier Transform-NMR spectrometer. DMSO was used as a solvent (s – singlet, d – doublet, m – multiplet). The in-vitro antioxidant activity was performed by DPPH, 5 H2O2 peroxide method, 6 NO2 scavenging method, 7 lipid peroxidation, 8 super oxide method, 9 ABTS method, 10 the standard procedure was followed for the determination of

free radical scavenging activity. of The synthesized compounds were evaluated the cytotoxic activity against MCF-7 and BT-549, ZR-75 cell lines by MTT assay method by 96 cell titer method. The cell viability was read by ELISA reader.11 The percentage growth inhibition was calculated in different concentrations. The CTC50 value was generated from the dose response curves. The cells were procured from the National Center for Cell Sciences (NCCS), Pune, India. The synthetic compounds were characterized by the determination of melting point, TLC, solubility, UV, IR and NMR. The analytical data showed satisfied reaction completions of the pure final compounds (Table 1). Qa: Rf = 0.71, MP = 248 °C–252 °C, λmax (UV) = 234.3 nm, IR (KBr) cm−1: 3119 cm−1 (NH stretching) 3040 cm−1 (CH stretching) 1699 cm−1 (C O), 741 cm−1, 777 cm−1, 675 cm−1 (aromatic ring).
