Design synthesis and biological

A benzothiazole ring plays an important role in pharmacological target diseases, including metabolic diseases, cancer, anti-inflammatory, neurodegeneration, viral diseases, bacterial infections, fibrosis, and thrombosis. Hydrazone-hydrazide derivatives are present in numerous biological molecules and play a significant role in medicine and pharmacology.

The octadecaneuropeptide (ODN; QATVGDVNTDRPG LLDLK) and its C-terminal octapeptide (OP; RPGLLDLK), which exert anxiogenic activity, have been previously shown to increase intracellular calcium concentration ([Ca21]i) in cultured rat astrocytes through activation of a metabotropic receptor positively coupled to phospholipase C. It has also been found that the [D -Leu5]OP analog possesses a weak antagonistic activity. The aim of the present study was to synthesize and characterize cyclic analogs of OP and [D -Leu5]OP.

important regulators of biological processes in animals and plants. MiRNAs regulate gene expression at the posttranscriptional level by binding to mRNAs and either inhibit translation or modify the stability of the mRNA. Due to the important biological role of miRNAs it is of great interest to study their expression level in the cells. Furthermore, miRNAs have been associated with cancer and other diseases [1] and miRNA expression can help in the diagnosis and prognostic of human disease [2,3].
