Two series of N-(aryl)-1-(hydroxyalkyl)pyrrolidine-2-carboxamides (2a-2g and 3a-3g) and 1,4-disubstituted 1,2,3-triazoles (5a-5h and 8a-8h) were synthesized. All the compounds, containing a lipophilic tail and a polar headgroup, were evaluated as sphingosine kinase (SphK) inhibitors by assessing their ability to interfere with the acetylcholine (Ach) induced relaxation of aortic rings pre-contr...
A series of new 4-(5-(3-cyano-4-isobutoxyphenyl)-4-methylthiazole-2-carbonyl)-N-(substituted phenyl)piperazine-1-carboxamides 8(a-e)/carbothioamides 8(f-j) were accomplished for biological interest by the simple addition of active functionalized arylisocyanates 7(a-e)/arylisothiocyanates 7(f-j) with 2-isobutoxy-5-(4-methyl-2-(piperazine-1-carbonyl)thiazol-5-yl)benzonitrile (4). Compound 4 was s...
BACKGROUND & OBJECTIVE Nasopharyngeal carcinoma (NPC) is an epithelial neoplasm with high occurrence rates in southern China. The disease often metastasizes to regional lymphnodes at a very early stage. Local recurrences and metastasis occur frequently in patients with NPC and are a leading cause of death, despite improvements on treatment modalities. The molecular mechanism underlying the meta...
OBJECTIVE This study aimed to determine the expression, clinical significance, and possible biologic function of microRNA-324-3p in nasopharyngeal carcinoma (NPC) tissues. METHODS In total, 54 NPC and 35 control tissues were collected. The correlation between miR-324-3p expression and the clinicopathologic characteristics was analyzed. A dual-luciferase reporter gene assay was employed to exa...
Synthesis and antibacterial activity of some novel urea and thiourea derivatives (7a-7k, 8a-8f) of anacardic acid prepared from commercially available anacardic acid which is obtained from natural product Cashew Nut Shell Liquid (CNSL). Compounds (7a-7k, 8a-8f) were tested for Gram positive and Gram negative bacterial cultures. Most of the compounds were showed active compared with standard dru...
Squamous cell carcinoma antigen 1 (SCCA1) is implicated in the growth, differentiation and metastasis of squamous cell carcinoma. Previously we found that SCCA1 protein level was lower in nasopharyngeal carcinoma (NPC) than in nasopharyngeal epithelial tissue. This study aimed to investigate the mechanism by which SCCA1 expression is downregulated in NPC. Four NPC cell lines including CNE1, CNE...
Nasopharyngeal carcinoma (NPC) is an Epstein-Barr virus-associated malignancy occurring at high incidence in Southeast Asia and southern China. In spite of the good response to radio- and chemo-therapy at the early stage, resistance and recurrence develop in NPC patients in the advanced setting. Cancer stem cells (CSCs) play an important role in drug resistance and cancer recurrence. Here we re...
