Lee, Yoon-Suk; Park, Sun Min; Kim, Hwan Mook; Park, Song-Kyu; Lee, Kiho; Lee, Chang Woo; Kim, Byeang Hyean published the article 《C5-Modified nucleosides exhibiting anticancer activity》. Keywords: nucleoside synthesis iododeoxyuridine human antitumor click cycloaddition isoxazole triazole.They researched the compound: 1-(Bromomethyl)-4-ethylbenzene( cas:57825-30-6 ).Quality Control of 1-(Bromomethyl)-4-ethylbenzene. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:57825-30-6) here.
We describe (i) a simple method for the synthesis of C5-modified nucleosides, e.g. I, from 5-iodo-2′-deoxyuridine and (ii) their activity against six types of human cancer cell lines (HCT15, MM231, NCI-H23, NUGC-3, PC-3, ACHN). We generated nitrile oxides in situ from oximes using a com. bleaching agent; their cycloaddition with 5-ethynyl-2′-deoxyuridine yielded isoxazole derivatives possessing activity against the cancer cell lines. We synthesized several azides from benzylic bromides and their click reactions with 5-ethynyl-2′-deoxyuridine provided triazole derivatives
