239101-34-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 239101-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,9,1,0 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 239101-34:
(8*2)+(7*3)+(6*9)+(5*1)+(4*0)+(3*1)+(2*3)+(1*4)=109
109 % 10 = 9
So 239101-34-9 is a valid CAS Registry Number.

Bisebromoamide, a potent cytotoxic peptide from the marine cyanobacterium lyngbya sp.: Isolation, stereostructure, and biological activity

Teruya, Toshiaki,Sasaki, Hiroaki,Fukazawa, Hidesuke,Suenaga, Kiyotake

supporting information; experimental part, p. 5062 - 5065 (2010/01/06)

A novel cytotoxic peptide, termed bisebromoamide (1), has been Isolated from the marine cyanobacterium Lyngbya sp. Its planar structure was determined by 1D and 2D NMR spectroscopy. The absolute stereostructure of 1 was determined by chemical degradation

Effects of C-4 stereochemistry and C-4' hydroxylation on the iron clearing efficiency and toxicity of desferrithiocin analogues

Bergeron, Raymond J.,Wiegand, Jan,McManis, James S.,McCosar, Bruce H.,Weimar, William R.,Brittenham, Gary M.,Smith, Richard E.

, p. 2432 - 2440 (2007/10/03)

Additional structure-activity studies of desferrithiocin analogues are carried out. The effects of stereochemistry at C-4 on the ligands' iron clearing efficiency are reviewed and assessed using the enantiomers 4,5- dihydro-2-(2,4-dihydroxyphenyl)thiazole-4(R)-carboxylic acid and 4,5-dihydro- 2-(2,4-dihydroxyphenyl)thiazole-4(S)-carboxylic acid. The utility of 4'- hydroxylation as a method of reducing the toxicity of desazadesferrithiocin analogues is also examined further with the synthesis and in vivo comparison of 4,5-dihydro-2-(2-hydroxyphenyl)-4-methylthiazole-4(S)-carboxylic acid, which is the natural product 4-methylaeruginoic acid, and 4,5-dihydro-2- (2,4-dihydroxyphenyl)-4-methylthiazole-4(S)-carboxylic acid. The stereochemistry at C-4 is shown to have a substantial effect on the iron clearing efficiency of desferrithiocin analogues, as does C-4'-hydroxylation on the toxicity profile. All of the compounds are evaluated in a bile-duct- cannulated rodent model to determine iron clearance efficiency and are carried forward to the iron-overloaded primate for iron clearing measurements. On the basis of the results of the present work, although 4,5- dihydro-2-(2,4-dihydroxyphenyl)thiazole-4(S)-carboxylic acid is still the most promising candidate for clinical evaluation, 4,5-dihydro-2-(2,4- dihydroxyphenyl)4-methylthiazole-4(S)-carboxylic acid (4'- hydroxydesazadesferrithiocin) also merits further preclinical assessment.
