摘要:
The present invention provides compounds of Formula I and related compositions and methods. Formula (I). R 1 and R 2 each refer to a branched or unbranched carbon chain of from 1 to 20 carbons having at least one basic function; R 1 and R 2 are the same or different; X 1 and X 2 are independently selected from H and -CO-Z, where Z is a peptide moiety incorporating from 1 to 5 amino acids, or a pharmaceutically acceptable salt thereof; X 1 and X 2 are the same or different; M is a divalent metal cation selected from magnesium (Mg 2 + ), calcium (Ca2+), and zinc (Zn 2+ ); A and B are each a molecule having at least one acidic function, either A or B, but not both, may be absent, and when both A and B are present, A and B may be the same or different. In a particular embodiment, at least one of "A" and "B" or both are fatty acids. A representative example of the application is the compound Magnesium Lysinate bis docosapentaenoic acid shown hereafter, Formula; The complexes of the application are intended for pharmaceutical compositions or as food additive, notably to treat conditions responsive to treatment with polyunsaturated fatty acids.

摘要:
The present invention provides a novel method for preparing highly pure calcobutrol using an intermediate (butrol) of gadobutrol without using highly pure gadobutrol. The present invention is capable of obtaining highly pure calcobutrol with high yield through a simple and environment-friendly process, and thus can easily be mass produced.
