Anti-Cancer Agents in Medicinal Chemistry (Formerly Current Medicinal Chemistry - Anti-Cancer Agents) - Volume 15, Issue 2, 2015

Prostate cancer possesses the highest occurrence rate and is the second-paramount disease that causes canceraffiliated death among men in the United States. Approximately 30,000 men die each year of castration-resistant prostate cancer due to the inevitable progression of resistance to first-line treatment with docetaxel. The safety profile of dietary curcumin in humans has been well-documented, and its therapeutic pros Read More

As a newly discovered tumor-associated gene, p42.3 was originally ascertained in gastric cancer cell line BGC823 and has been confirmed as a cell cycle-dependent gene that is overexpressed in many human tumor cell lines and embryonic tissues. p42.3 can regulate the level of relevant cycle-dependent proteins and promote malignant transformation of cells. A variety of cellular functions, including cell proliferation, cell invasio Read More

The recent emergence of anticancer activity of thiourea derivatives have inspired the medicinal chemist to design and synthesize new thiourea derivatives. These thiourea based anticancer chemotherapeutics inhibit cancer propagation by acting as inhibitors of topoisomerase, protein tyrosine kinase, somatostatin agonists, sirtuins, and carbonic anhydrase (CA). This review summarizes the recent developments on the t Read More

Poly(ethylene glycol) is a water-soluble polymer. Due to its high safety and biocompatibility, it has been widely used to prepare amphiphilic copolymers for drug delivery. These copolymers can enhance water-solubility of hydrophobic drugs, improve their pharmacokinetic parameters and control their release from corresponding nanocarriers formed by its self-assembly. Anticancer drugs have some shortcomings such as lo Read More

Chronic lymphocytic leukemia (CLL) develops due to an imbalance between apoptosis and proliferation of B lymphocytes. Chrysin induced apoptosis in leukemia cell lines such as U937, MO7e, THP-1 and HL-60, but there has not yet been data demonstrating the apoptotic effect of chrysin on CLL cells. Therefore, in our investigation we examined the cytotoxicity of chrysin against two leukemia cell lines, MOLT-4 and JVM-13, periphe Read More

The all trans retinoic acid (ATRA) is found to have a promising regulatory effect on immune system and inflammatory responses in experimental research. The purpose of this study was to investigate whether this therapeutic efficiency of ATRA could be enhanced by encapsulating into a liposome formulation composed of Distearoyl-Lphosphatidylcholine (DSPC) and cholesterol utilizing a well-established mice model. The h Read More

Twenty-seven nitrated and non-nitrated compounds have been synthesized and tested for their growth inhibitory activity on three human cancer cells lines. Fourteen compounds were able to inhibit more than 50% of the growth of at least one of the cancer cell lines and five compounds exhibited high antiproliferative activity on human cancer cell lines (IC50 < 8.5 μM). The cytotoxicity of the compounds on Vero cell line w Read More

Protein kinase C-δ (PKC-δ) and PKC-ε are reported to be effective in cancer prevention via S-thiolationmediated mechanisms. This may be through stimulation of the pro-apoptotic, tumor-suppressive isozyme PKC-δ and/or inactivation of the growth stimulatory, oncogenic isozyme PKC-ε. We investigated oxidative regulatory responses of PKC-δ and PKC-ε to cystine dimethyl ester (CDME), a metabolic precursor of cystine, whic Read More

This study aimed to isolate terpenoids from Alisma orientalis (Sam.) Juzep. and elucidate their antiproliferative activities, as well as structure-activity relationships. Fourteen protostane-type triterpenoids were isolated from the rhizome of A. orientalis. Among these triterpenoids, alisol A (1), alisol A 24-acetate (2), alisol B (3), alisol B 23-acetate (4), and alisol G (8) presented inhibitory effects on cancer cell lines tested. Compounds 3 a Read More

We examined the anticancer effects of limonin and imperatorin on various human cancer cells by MTT assay, and the results showed that imperatorin inhibited the cell growth of SNU 449 (liver cancer) and HCT-15 (colon cancer) cells in a dose-dependent manner, while limonin had less effect. Exposure of different concentrations of limonin and imperatorin caused morphological changes in cancer cells, but not in normal Read More

The newly synthesized naftopidil analogue HUHS1015 reduced viability of MKN28 and MKN45 human gastric cancer cells in a concentration (0.3-100 μM)-dependent manner, with the potential greater than that for naftopidil. In the cell cycle analysis, HUHS1015 significantly increased the proportion at the subG1 phase of cell cycling in MKN28 cells. In the flow cytometry using propidium iodide (PI) and annexin V, HUHS1015 Read More

The aim was to analyse the efficacy of piceatannol (PIC) loaded chitosan (CS)/poly(lactic acid)(PLA) nanoparticles (CS/PLA-PIC NPs) in zebra fish embryos exposed to aflatoxin B1 (AFB1). FTIR confirmed the chemical interaction between the polymers and drug. SEM showed the size of CS/PLA-PIC NPs approximately 87 to 200nm, compared to CS-PLA NPs of 150nm size. The size was further affirmed as 127nm (CS-PLA NPs) and Read More

One known cyclic peptide, beauvericin, was isolated from the secondary metabolites of mangrove endophytic fungi Fusarium sp. (No. DZ27) in South China Sea. Its structure was determined by spectral analyses and comparisons with reference data from literatures. Beauvericin inhibited growth of KB and KBv200 cells potently with IC50 values of 5.76 ± 0.55 and 5.34 ± 0.09 μM, respectively. Furthermore, beauvericin indu Read More

With the successful use of gefitinib and erlotinib in clinic, some potent EGFR tyrosine kinase receptor inhibitors have gained widespread concern in the treatment of ovarian or non-small-cell lung cancer. However, the emergence of EGFR-activating mutations resist to the drugs, there is an impending need to design new inhibitor targeted EGFR. Furthermore, the understanding of mutual effect between EGFR and drug has be Read More
