Abstract:
The invention provides a compound of formula I: or a salt thereof, wherein R 1 , R 2 , R 3 , R 4 , L 1 , L 2  and Y have any of the values described in the specification, as well as compositions comprising a compound of formula I. The compounds are useful for labeling penicillin-binding proteins (PBPs).

Claim (Index 1):
A compound of formula I: or a salt thereof, wherein: R 1  is H, (C 1 -C 6 )alkyl, (C 1 -C 6 )alkoxyl, aryl, heteroaryl, or 4-8 membered heterocycle; wherein the (C 1 -C 6 )alkyl is optionally substituted with one or more groups independently selected from halo, \u2014OR a , \u2014CN, \u2014NO 2 , -oxo-, \u2014N(R a ) 2 , \u2014CO 2 R a , aryl, heteroaryl, or 4-8 membered heterocycle, wherein any aryl, heteroaryl, and 4-8 membered heterocycle is optionally substituted with one or more groups independently selected from halo, \u2014OR a , \u2014CN, \u2014NO 2 , -oxo-, \u2014N(R a ) 2 , or \u2014CO 2 R a ; R 2  is H or (C 1 -C 6 )alkyl; R 3  is H or (C 1 -C 6 )alkyl; R 4  is H, (C 1 -C 6 )alkyl, (C 1 -C 6 )alkoxyl, aryl, heteroaryl, or 4-8 membered heterocycle; wherein the (C 1 -C 6 )alkyl is optionally substituted with one or more groups independently selected from halo, \u2014OR b , \u2014CN, \u2014NO 2 , -oxo-, \u2014N(R b ) 2 , \u2014CO 2 R b , aryl, heteroaryl, or 4-8 membered heterocycle, wherein any aryl, heteroaryl, and 4-8 membered heterocycle is optionally substituted with one or more groups independently selected from halo, \u2014OR b , \u2014CN, \u2014NO 2 , -oxo-, \u2014N(R b ) 2 , or \u2014CO 2 R b ; L 1  is absent or (C 1 -C 4 )alkylene; L 2  is absent or a linking group; Y is \u2014N 3 , (C 2 -C 6 )alkynyl, 3-8 membered cycloalkyl comprising at least one triple bond, 1,2,4,5-tetrazinyl which is optionally substituted with (C 1 -C 6 )alkyl, biotin, or a detectable group; each R a  is independently hydrogen or C 1-4  alkyl; or two R a  groups taken together with the nitrogen to which they are attached form pyrrolidinyl, piperidinyl, piperazinyl or morpholinyl; and each R b  is independently hydrogen or C 1-4  alkyl; or two R b  groups taken together with the nitrogen to which they are attached form pyrrolidinyl, piperidinyl, piperazinyl or morpholinyl.
