Antineoplastic natural products and the analogs: Antineoplastic natural products and the analogs. VIII. Synthesis of some coumarins and their cytotoxic activities on L1210 cell. Kang, K. S.; Ahn, B. Z. (Coll. Pharm., Chungnam Natl.There are some reagents with their cas registry numbers 15233-65-5 and 305-01-1 are used in this study. Univ., Taejon 300-31, S. Korea). Arch. Pharmacal Res., 9(2), 115-17 (English) 1986. CODEN: APHRDQ. ISSN: 0253-6269. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacology) Section cross-reference(s): 25, 27 Some coumarins were synthesized for the screening of their cytotoxic activities against L1210 cell. Of the coumarins tested, esculetin (I) [305-01-1] and daphnetin (7,8-dihydroxycoumarin) [486-35-1] as coumarins with dioxygenated A-ring, and 6-acetoxy-5,7-dimethoxycoumarin [28752-90-1] and 5,7-dimethoxy-6-hydroxycoumarin [486-28-2] as trioxygenated ones, show considerable cytotoxic activities, ED 50 being 4.3, 8.8, 17.2, and 5.5 mg/mL in the same order as the substances. The extent of oxygenation of the A-ring and the positions of the O functions eventually play an important role for the cytotoxic activity. .

The bleaching and photostabilization of high-yield pulp by sulfur compounds: The bleaching and photostabilization of high-yield pulp by sulfur compounds. I. Reaction of thioglycerol with model quinones. Cole, Barbara J. W.; Zhou, Chen; Fort, Raymond C., Jr. 15233-65-5 and 186804-73-9 are cas registry numbers. These chemicals are also mentioned in this article. (Dep. Chem., Univ. Maine, Orono, ME 04469, USA). Journal of Wood Chemistry and Technology, 16(4), 381-403 (English) 1996 Dekker. CODEN: JWCTDJ. ISSN: 0277-3813. DOCUMENT TYPE: Journal CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Section cross-reference(s): 25 The reaction of thioglycerol with quinones selected to model the chromophores present in high-yield pulp has been investigated. The reaction is rapid and complex, involving initial Michael addn., aromatization of the adducts to hydroquinones, and reoxidn. of those hydroquinones to new chromophores. The Michael addn. is responsible for the bleaching effect of thioglycerol upon pulp, and the reoxidn. is responsible for the eventual development of more intense color by treated pulp. Semi-empirical and ab initio MO calcns. have been used as an aid to rationalizing the exptl. results. .
