Pyrazolopyrimidine antibacterial agents
Pyrazolopyrimidine compounds for inhibition of isoprenoid biosynthesis have a formula (I) or a pharmaceutically acceptable salt thereof. In formula (I), R 1 includes an alkyl group and R 2 includes an optionally substituted moiety selected from the group consisting of an optionally substituted benzyl group, an optionally substituted phenethyl group, an optionally substituted ethanol group, an optionally substituted ethyl acetate group, an optionally substituted methyl furan group, an optionally substituted 3-ethyl indole group, and a lower alkyl group. Compositions containing pyrazolopyrimidine compounds and methods for using pyrazolopyrimidine compounds are described.
1. A compound of formula (I)
or a pharmaceutically acceptable salt thereof;
wherein R 1 is methyl; and
wherein R 2 has a formula (VIII)
2. A compound of formula (I)
or a pharmaceutically acceptable salt thereof;
wherein R 1 comprises an alkyl group;
wherein R 2 comprises an optionally substituted group of formula (III)
and
wherein the group of formula (III) comprises a lipophilic electron withdrawing group at each of its 2-position and 4-position.
