Nonionic radiographic contrast agents
New nonionic radiographic contrast agents having the formula STR1 wherein Y is a single bond, –CH2 CH2 –, –CH2 O–, –OCH2 –, STR2 –CH2 –, –CH2 –CH2 –CH2 –, –O– or STR3 R1, R1 ‘ and R2 are the same or different and are hydrogen, alkyl or hydroxyalkyl. Hydroxyalkyl refers to such alkyl groups having 1 or more hydroxy groups. Preferred hydroxyalkyl groups include: STR4 R3 and R4 are the same or different and are hydrogen, methyl or –CH2 CH2 OH; R5 is hydrogen, alkyl, –CH2 CH2 OH, CH2 OH or OH and R6 is alkyl, –CH2 CH2 OH, CH2 OH, OH or hydrogen and may be the same or different than R5 and m is zero or one, with the proviso that no methylene or methine carbon atom of the heterocyclic ring is attached to both a nitrogen and an oxygen atom with the additional proviso that when Y is a single bond, m is not zero. These new contrast agents are water soluble and have desirable low osmolality and anticoagulant properties.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 166591-85-1, and how the biochemistry of the body works.Electric Literature of 166591-85-1
