Claims
- 1. A compound of the formula ##STR6## wherein R.sub.1 and R.sub.2 are independently selected from alkyls of one to six carbons;
- R.sub.3 is selected from hydrogen, dimethylaminomethyl and 2,3-dihydroxypropyloxy;
- R.sub.4 is selected from hydroxy, cyano, --NHCON(R.sub.5).sub.2, --C(.dbd.NH)N(R.sub.5).sub.2, and --NHC(.dbd.NH)N(R.sub.5).sub.2, wherein each R.sub.5 is independently hydrogen or an alkyl group of one to three carbons, with the provisos that when R.sub.3 is hydrogen, R.sub.4 may not be hydroxy, when R.sub.3 is dimethylaminomethyl, R.sub.4 is hydroxy and when R.sub.3 is 2,3-dihydoxypropyloxy, R.sub.4 is hydrogen
- and pharmaceutically acceptable salts of such compounds.
- 2. The compound of claim 1 wherein R.sub.1 and R.sub.2 are propyl.
- 3. The compound of claim 1 wherein R.sub.1 and R.sub.2 are n-propyl, R.sub.3 is hydrogen and R.sub.4 is --NHCON(R.sub.5).sub.2.
- 4. The compound of claim 1 wherein R.sub.1 and R.sub.2 are n-propyl, R.sub.3 is hydrogen and R.sub.4 is C(.dbd.NH)N(R.sub.5).sub.2.
- 5. The compound of claim 1 wherein R.sub.1 and R.sub.2 are not the same and are selected from n-propyl and methyl.
- 6. The compound of claim 1 wherein R.sub.1 and R.sub.2 are n-propyl, R.sub.3 is hydrogen and R.sub.4 is selected from cyano, --NHCON(R.sub.5).sub.2, --C(.dbd.NH)N(R.sub.5).sub.2 and --NHC(.dbd.NH)N(R.sub.5).sub.2.
- 7. The compound of claim 1 wherein R.sub.1 and R.sub.2 are n-propyl and R.sub.3 is 2,3-dihydroxypropyloxy.
- 8. The compound of claim 1 wherein R.sub.1 and R.sub.2 are n-propyl, R.sub.3 is dimethylaminomethyl and R.sub.4 is hydroxy.
