It has previously been shown that anthranilamide-pyrazolo[1,5-a]pyrimidine conjugates activate p53 and cause apoptosis in cervical cancer cells such as HeLa and SiHa. Here we establish the role of these conjugates in activating p53 pathway by phosphorylation at Ser15, 20 and 46 residues and downregulate key oncogenic proteins such as MYCN and Mdm2 in IMR-32(More)
By applying a methodology, a series of benzothiazole-pyrrole based conjugates (4a-r) were synthesized and evaluated for their antiproliferative activity. Compounds such as 4a, 4c, 4e, 4g-j, 4m, 4n, 4o and 4r exhibited significant cytotoxic effect in the MCF-7 cell line. Cell cycle effects were examined for these conjugates at 2 μM as well as 4 μM(More)
A series of novel pyrano[3,2-c]carbazole derivatives have been synthesized by a simple one-pot, three component reaction of aromatic aldehydes, malononitrile-ethyl cyanoacetate and 4-hydroxycarbazoles catalyzed by triethylamine. The antiproliferative activity of the derivatives on various cancer cell lines such as MDA-MB-231, K562, A549 and HeLa was(More)
BORIS/CTCFL is a vital nucleotide binding protein expressed during embryogenesis and gametogenesis. BORIS/CTCFL is the paralogue of transcriptional repressor protein CTCF, which is aberrantly expressed in various malignancies and primarily re-expressed in cancer stem cells (CSCs). The mechanism behind regulation of BORIS in various cancer conditions and(More)
AIMS miRNAs are small non-coding RNA molecules that regulate post-transcriptional gene expression. Here we have made an endeavor to search whether any miRNAs are involved in the regulation of BMI1 in breast cancer that leads to mitochondrial dependent apoptotic cell death. MAIN METHODS Renilla luciferase reporter assay was performed to detect the(More)
A series of anilinonicotinyl linked pyrazolo[1,5-a]pyrimidine conjugates (6a-x) were synthesized and evaluated for their antiproliferative activity. Some of these conjugates exhibited promising cytotoxic effects in the MCF-7 cell line and among these 6a and 6c exhibited significant effects, apart from G2/M cell cycle arrest. Interestingly they showed(More)
