-
Paragraph 0071-0073, (2018/02/04)
The invention provides a water-soluble monodemethoxycurcumin derivative as shown in general formula I and a pharmaceutically acceptable salt thereof. The compound has higher water solubility as well as high antitumor activity, has a function of inhibiting human gastric carcinoma cells MGC-803, human hepatocellular carcinoma cells Bel-7402, human chronic leukemia granulocytes K562 and human glioma U87 to different extents, and can be used for preparing an antitumor medicament, and the IC50 (Inhibitory Concentration 50) reaches the level of 1 [mu]M.
Improved utility of photolabile solid phase synthesis supports for the synthesis of oligonucleotides containing 3'-hydroxyl termini

Oligonucleotides are synthesized on, and cleaved from, a solid phase support (6) using the o-nitrobenzyl intramolecular photochemical redox reaction. The yields of isolated oligonucleotides relative to yields obtained using conventional hydrolytic cleavage vary between 67% and 82.5%. Synthesis of oligonucleotides using phosphoramidites that do not contain N-benzoyl protecting groups enables one to photolytically cleave the biopolymers in good yields using a commonly available UV irradiation source. Tritium labeling indicates that less than 3% thymidine·thymidine photodimers are formed during photolytic cleavage of polythymidylates from 6 using a transilluminator. No UV-induced damage is detected via HPLC analysis of enzymatically digested oligonucleotides that were obtained following photolytic cleavage from 6.
