Abstract: The invention is related to 1-O-alkyl-3-amino-propan-1.

Abstract: Compounds and compositions containing them, for insecticidal control having the formula ##STR1## in which R.sub.1 is an alkyl group having from 1 to 3 carbon atoms, R.sub.2 is an alkyl group having from 1 to 6 carbon atoms, and R.sub.3 and R.sub.4 are independently alkyl groups having from 1 to 6 carbon atoms, or R.sub.3 and R.sub.4 taken together form a ring having the formula ##STR2## in which m and n are each integers from 1 to 3 and X is oxygen or --CH.sub.2 --, together with insecticidal compositions containing such compounds, and methods for controlling insects.

Abstract: New phospholipid derivatives represented by the formula: ##STR1## wherein R.sup.1 is alkyl, alkoxy, alkylthio or alkylsulfonyl;R.sup.2 is hydrogen, hydroxy, alkoxy, lower alkanoyloxy or lower alkylcarbamoyloxy;n is 0 or 1;R.sup.3 is hydroxy or protected hydroxy; andR.sup.4 is lower alkoxy or lower alicyclic-oxy group which is substituted with 2 or more hydroxy or protected hydroxy groups, and may be substituted with lower alkoxy or another alicyclic-oxy group having two or more hydroxy or protected hydroxy groups, in which the alicyclic ring may contain an oxygen atom;and pharmaceutically acceptable salt thereof, which exhibit antitumor activity.

Abstract: Glycerol derivatives, inclusive of salts thereof, of the formula ##STR1## wherein R.sup.1 is alkyl or alkylcarbamoyl containing 10 to 30 carbon atoms, R.sup.2 and R.sup.3 are independently hydrogen, C.sub.1-6 alkyl or, taken together with the adjacent nitrogen atom, form cyclic amino, and ##STR2## represents cyclic ammonio, and of the formula ##STR3## wherein R.sup.1 is as defined above, R.sup.2' and R.sup.3' are C.sub.1-6 alkyl or, taken together with the adjacent nitrogen atom, form cyclic amino and R.sup.4', R.sup.5' and R.sup.6' are independently hydrogen or C.sub.1-6 alkyl, are useful as antihypertensive agents.
