Guided by bioisosterism and pharmacokinetic parameters, we designed and synthesized a series of novel benzamide derivatives. Preliminary in vitro studies indicated that compounds 10b and 10j show significant inhibitory bioactivity in HepG2 cells (IC50 values of 0.12 and 0.13 μM, respectively). Compounds 10b and 10j induced the expression of HIF-1α protein and downstream target gene p21, and upregulated the expression of cleaved caspase-3 to promote tumor cells apoptosis.

Toxicarioside N (Tox N), a natural product extract from Antiaris toxicaria, has been reported to induce apoptosis in human gastric cancer cells. However, the mechanism and actual role of autophagy in Tox N-induced apoptosis of human gastric cancer cells remains poorly understood. In the current study, we demonstrated that Tox N could induce autophagy by inhibiting the Akt/mTOR signaling pathway in SGC-7901 cells. Moreover, we found that the inhibition of autophagy by 3-methyladenine, an autophagy inhibitor, enhanced Tox N-induced apoptotic cell death...

Diabetes mellitus is globally approaching epidemic proportions and acts as a major cause of a number of serious health problems diagnosed as diabetic complications. The current oral drugs in the treatment of diabetes and its complications could meet some but not all of the patients' needs, and the development of novel drugs with a hypoglycemic effect is urgently required. Silibinin, a flavonolignan traditionally used for the treatment of gallbladder and hepatic diseases, was reported to improve glycemic homeostasis by improving the activity of pancreatic β-cells, increasing insulin sensitivity of liver and muscle cells, and decreasing lipid deposition in adipocytes...

The discovery of sequence specific nucleases such as ZFNs, TALENs, and CRISPR/Cas9 has revolutionized genome editing. The CRISPR/Cas9 system has particularly emerged as a highly simple and efficient approach towards generating genome-edited animal models of most of the experimental species. The limitation of these novel genome editing tools is that, till date, they depend on traditional pronuclear injection (PI)-based transgenic technologies developed over the last three decades. PI requires expensive micromanipulator systems and the equipment operators must possess a high level of skill...

Communication between tumor cells and stromal cells is crucial to tumor development and progression. Fibroblasts and macrophages are the most common stromal cells in the tumor microenvironment. Endothelial cells are another type of stromal cell in the tumor microenvironment required for angiogenesis via interaction with tumor cells. Tumor angiogenesis provides not only oxygen and nutrients for tumor cells but also the necessary anchorage to facilitate tumor metastasis. The present review summarizes studies on the crosstalk between cancer cells and endothelial cells with a focus on implications for tumor progression...

A docetaxel (DTX) liposomal formulation composed of egg phosphatidylcholine, sodium deoxycholate, and stearylamine was developed. Eudragit (0.5%) was coated to deliver the drug to the region between the distal small intestine and the colon. Lyophilized trehalose and mannitol were used as cryoprotectants because they preserve the particle integrity and good appearance. In vitro release studies showed that the amount of drug released from the coated liposomes was low in solution 1, which simulated the pH condition of the stomach...

Aspirin is one of the oldest drugs for the treatment of inflammation, fever, and pain. It is reported to covalently modify COX-2 enzyme by acetylating a serine amino acid residue. By virtue of aspirin's acetylating potential, we for the first time developed novel acetyl-donating HDAC inhibitors. In this study, we report the design, synthesis, in silico docking study, and biological evaluation of acetyl-donating HDAC inhibitors. The exposure of MDA-MB-231 cells with compound 4c significantly promotes the acetylation of α-tubulin and histone H3, which are substrates of HDAC6 and HDAC1, respectively...

The aim of this work was to evaluate the synthesis and structure-activity relationship of 4-((2,4-dioxothiazolidin-5-ylidene)methyl)phenyl 2-phenylacetate derivatives as potential wound-healing agents. The IC50 values of the lead compounds ranged from 0.01 to 0.05 µM. These compounds also increased the levels of extracellular prostaglandin E2 (PGE2 ) in A549 cells. Among the synthesized compounds, compounds 66, 67, 69, and 86 increased PGE2 levels 3- to 4-fold of those achieved with the negative control. Introduction of a halogen at the intermediate phenyl ring, compounds 66, 67, 69, and 86 resulted in higher IC50 values, which indicated lower cytotoxicity than that observed upon the introduction of other substituents at the same position...

Rufinamide (RUF) is a structurally unique anti-epileptic drug, used in the treatment of seizure disorders such as Lennox-Gastaut syndrome. In the present study, we investigated whether RUF protected against excitotoxic neuronal damage in the mouse hippocampal CA3 region after intraperitoneal kainic acid (KA) injection. Treatment with 25, 50 and 100 mg/kg RUF significantly decreased the KA-induced neuronal death in the hippocampal CA3 region in a dose-dependent manner. In addition, 100 mg/kg RUF treatment reduced the KA-induced oxidative stress-related increase of MDA level and decrease of total SOD activity in the hippocampus...

Drug-induced diabetes is widely reported in clinical conditions, and it is becoming a global issue because of its potential to increase the risk of severe cardiovascular complications. However, which drug mechanisms exert their diabetogenic effects and why the effects present significant inter-individual differences remain largely unknown. Pharmacogenomics, which is the study of how genomic variation influences drug responses, provides an explanation for individual differences in drug-induced diabetes. We highlight that pharmacogenomics can be involved in regulating the expression of genes in signaling pathways related to the pharmacokinetics or pharmacodynamics of drugs or the pathogenesis of diabetes, contributing to the differences in drug-induced glucose impairment...

Targeted genome editing by clustered regularly interspaced short palindromic repeats (CRISPR-Cas9) raised concerns over off-target effects. The use of double-nicking strategy using paired Cas9 nickase has been developed to minimize off-target effects. However, it was reported that the efficiency of paired nickases were comparable or lower than that of either corresponding nuclease alone. Recently, we conducted a systematic comparison of the efficiencies of several paired Cas9 with their corresponding Cas9 nucleases and showed that paired D10A Cas9 nickases are sometimes more efficient than individual nucleases for gene disruption...

The key to successful drug discovery and development is to find the most suitable animal model of human diseases for the preclinical studies. The recent emergence of engineered endonucleases is allowing for efficient and precise genome editing, which can be used to develop potentially useful animal models for human diseases. In particular, zinc finger nucleases, transcription activator-like effector nucleases, and the clustered regularly interspaced short palindromic repeat systems are revolutionizing the generation of diverse genetically-engineered experimental animals including mice, rats, rabbits, dogs, pigs, and even non-human primates that are commonly used for preclinical studies of the drug discovery...

Cancer is a leading cause of death worldwide. Despite many advances in the field of cancer therapy, an effective cure is yet to be found. As a more potent alternative for the conventional small molecule anti-cancer drugs, pro-apoptotic peptides have emerged as a new class of anticancer agents. By interaction with certain members in the apoptotic pathways, they could effectively kill tumor cells. However, there remain bottleneck challenges for clinical application of these pro-apoptotic peptides in cancer therapy...

Cassia obtusifolia L. seed is one of the most popular traditional Chinese medicine for mutagenicity, genotoxicity, hepatotoxicity, and acute inflammatory diseases. We evaluated the hepatoprotective activity of anthraquinone and naphthopyrone glycosides isolated from the butanol fraction of C. obtusifolia seeds and explored their effects on cell signaling pathways. Continuous chromatographic separation led to the isolation of 1-desmethylaurantio-obtusin 2-O-β-D-glucopyranoside (1), rubrofusarin 6-O-β-D-apiofuranosyl-(1 → 6)-O-β-D-glucopyranoside (2) and rubrofusarin 6-O-β-gentiobioside (3)...

Oxidative stresses, such as reactive oxygen species, reactive electrophilic species, reactive nitrogen species, and reactive chlorine species, can damage cellular components, leading to cellular malfunction and death. In response to oxidative stress, bacteria have evolved redox-responsive sensors that enable them to simultaneously monitor and eradicate potential oxidative stress. Specifically, redox-sensing transcription regulators react to oxidative stress by means of modifying the thiol groups of cysteine residues, functioning as part of an efficient survival mechanism for many bacteria...
