摘要:
Compounds of the formula ##STR1## in which X is hydrogen or the radical CH.sub.2 OR.sup.5,R.sup.2, R.sup.3, R.sup.4 and R.sup.5 each independently is hydrogen or the radical ##STR2## Y is oxygen, sulphur, NH or CH.sub.2, and R.sup.1 and R.sup.6 each independently is an optionally substituted hydrocarbon radical having up to 50 carbon atoms, with the proviso that at least one of the radicals R.sup.1 and/or R.sup.6 contains between 9 to 50 carbon atoms,some of which are known, stimulate the immune system's response and antibody production.
摘要:
Compounds of the formula ##STR1## in which X is hydrogen or the radical --CH.sub.2 OR.sup.5,three of R.sup.2, R.sup.3, R.sup.4 and R.sup.5 each independently is hydrogen or ##STR2## and the fourth is ##STR3## Z each independently is oxygen, sulphur, NH or CH.sub.2, and R.sup.1, R.sup.6 and R.sup.7 each independently is an optionally substituted hydrocarbon radical having up to 50 carbon atoms,stimulate the immune system's response and antibody production.
摘要:
Novel compounds of the formula ##STR1## in which X is hydrogen or --CH.sub.2 --OR.sup.5,Z represents OR.sup.4, NH.sub.2 or ##STR2## R.sup.2, R.sup.3, R.sup.4 and R.sup.5 each independently is hydrogen or ##STR3## at least one of R.sup.2, R.sup.3, R.sup.4 and R.sup.5 being ##STR4## Y and W each independently is oxygen, sulphur, NH or CH.sub.2, and R.sup.1, R.sup.6, R.sup.7 and R.sup.8 each independently is an optionally substituted hydrocarbon radical with up to 50 C atoms,stimulate the immune system.
摘要:
Compounds of the formula ##STR1## in which R.sup.1 represents an optionally substituted, straight-chain or branched, saturated, monounsaturated or polyunsaturated alkyl radical, an optionally substituted, saturated or one- or polyunsaturated cycloalkyl radical or an optionally substituted aryl radical or aralkyl radical,X represents CH.sub.2, O, S, NH or N-alkyl with up to 20 C atoms,R.sup.2 has the meaning of R.sup.1, and can represent hydrogen if X denotes CH.sub.2, the radicals R.sup.3 independently of one another represent hydrogen, an acyl radical or alkyl radical with in each case up to 20 C atoms, a silyl radical and/or a phosphoric acid or phosphoric acid ester radical andR.sup.4 denotes hydrogen, methyl or --CH.sub.2 --OR.sup.3, with the proviso that one of the radicals R.sup.3 always represents a phosphoric acid or phosphoric acid ester radical, which stimulate a patient's immune system and are thereby effective in combating viral disease and bacterial infection.
