Patent ID: 7557097

Claim:
An isolated or chemically synthesized compound having the formula (Formula II): wherein: wherein: q is 0; p is 0 or 1; n is 2 or 3; k is 0; X is —N(H)— or —C(O)N(H)—; Z is O; R 2′ and R 3′ are independently selected from the group consisting of H, —OH, and —OSO 3 M; R 4′ is H, an alkyl having six carbons or less, —(CH 2 ) r OH, or —(CH 2 ) r OSO 3 M wherein r is 0, 1, or 2; R 5′ is —OH, —OSO 3 M, —CH 2 OH, or —CH 2 OSO 3 M; and M is a Na counterion; Y is —O—, —N(H)—, or —N(R 8′ )—; R 8′ is a branched or unbranched alkyl or a cycloalkyl; represents a single or double carbon-carbon bond between C4 and C5 or C5 and C6; represents a single, double, or a triple carbon-carbon bond between C22 and C23; at C3, C5, C7, C12, C20, and C24 represents a bond to the attached substituent that is either in front of (β) or behind (α) the plane of the paper, and defines the R or S absolute configuration of the carbon atom that bears the attached substituent; m is 1, 2, 3, or 4; with the proviso that R 1′ is not 2-(N-pyrrolidino)ethylamino.
