Spectrophotometric determination of antimalarials using quinones

Spectrophotometric determination of antimalarials using quinones. Sastry, B. S.Several substances are used for example 615-94-1 and 550-24-3 which are their cas registry numbers.; Rao, E. Venkata; Suryanarayana, M. V.; Sastry, C. S. P. (Dep. Pharm. Sci., Andhra Univ., Waltair 530 003, India). Pharmazie, 41(10), 739-40 (English) 1986. CODEN: PHARAT. ISSN: 0031-7144. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Five antimalarials, amodiaquine [86-42-0], chloroquine [54-05-7], primaquine [90-34-6], trimethoprim [738-70-5], and pyrimethamine [58-14-0] were detd. by spectrophotometry based on interaction of these drugs with any one of the 3 quinones, 2,5-dihydroxy-3-undecyl-1,4-benzoquinone (I) [550-24-3], 2,5-dihydroxy-1,4-benzoquinone (II) [615-94-1], and chloranilic acid to yield colored complexes. The absorbance was measured at 520, 500 and 540 nm for I, II and chloranilic acid, resp. I and II are suitable for detn. of all the 5 antimalarial drugs, while chloranilic acid is suitable for detn. of the 1st 4 drugs. Beer's law limits and regression equations and std. deviations are given. .

PRIORITY: DE 2003-10328667 26 Jun 2003. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) The invention relates to the use of benzoquinones or their derivs. or salts as the single oxidn. agent in substances for the oxidative treatment of hair and to substances contg. at least one o-benzoquinone. The invention also relates to a method for the permanent reshaping of hair using said substances. After said treatment, the hair has a uniform and lasting shape and does not have a bleached appearance. Thus hair samples were treated with a permanent waving soln. contg. 10 wt./wt.% thioglycolic acid for 15 min at 50°C; the hair was rinsed and fixation soln. was applied that contained: p-benzoquinone 1.00 g; phosphoric acid 0.04 g; water to 100.00 g. .
