Liu, Jingjing; Tian, Zhenwei; Liu, Tianzhou; Wen, Dacheng; Ma, Zhiming; Liu, Yuanda; Zhu, Jiaming published the artcile< CHSY1 is upregulated and acts as tumor promotor in gastric cancer through regulating cell proliferation, apoptosis, and migration>, HPLC of Formula: 2591-17-5, the main research area is prognosis CHSY1 XIAP cell proliferation migration metastatic gastric cancer; CHSY1; Gastric cancer; cell apoptosis; cell migration; cell proliferation.

Gastric cancer is one of the most frequently diagnosed malignant tumors, with rapid progression and poor prognosis. The role of chondroitin sulfate synthase 1 (CHSY1) in the development and progression of gastric cancer was explored and clarified in this study. The immunohistochem. anal. of clin. tissue samples as well as data mining of public database showed that CHSY1 was significantly upregulated in gastric cancer and associated with more advanced tumor stage and poorer prognosis. In vitro loss-of-function experiments demonstrated the inhibited cell proliferation, colony formation, cell migration, as well as the promoted cell apoptosis by CHSY1 knockdown. Moreover, recovery of CHSY1 expression could attenuate the regulatory effects induced by CHSY1 knockdown. Correspondingly, gastric cancer cells with CHSY1 knockdown showed reduced tumorigenicity and slower tumor growth in vivo. In conclusion, this study identified CHSY1 as a tumor promotor in gastric cancer, which may be utilized as a novel indicator of patients′ prognosis and therapeutic target for developing more effective drug for GC treatment.

Dessi, Alessio; Calamante, Massimo; Mordini, Alessandro; Zani, Lorenzo; Taddei, Maurizio; Reginato, Gianna published the artcile< Microwave-activated synthesis of thiazolo[5,4-d]thiazoles by a condensation/oxidation sequence>, Formula: C4H3NOS, the main research area is thiazolothiazole microwave preparation condensation oxidation.

A microwave-assisted preparation of sym. thiazolo[5,4-d]thiazoles from the corresponding aldehydes is presented. The two-step reaction sequence comprises the condensation of aldehydes with dithiooxamide followed by oxidation/aromatization with 1,4-benzoquinone derivatives The new procedure provides the desired products in good yields and in most cases allows reduction of the excess of aldehyde employed in the process compared to previous methodologies. For the first time, application of the reaction both on aromatic and aliphatic aldehydes is demonstrated.
