The present invention provides a novel carboxylic acid compound, a salt thereof or a hydrate of them useful as an insulin sensitizer, and a medicament comprising the compound as an active ingredient. That is, the present invention provides a carboxylic acid compound represented by the following formula, a salt thereof, an ester thereof or a hydrate of them. Wherein R1 represents a hydrogen atom, hydroxyl group, halogen, carboxyl group, or a C1-6 alkyl group etc., each of which may have one or more substituents; L represents a single bond, or a C1-6 alkylene group, a C2-6 alkenylene group or a C2-6 alkynylene group, each of which may have one or more substituents; M represents a single bond, or a C1-6 alkylene group, a C2-6 alkenylene group or a C2-6 alkynylene group, each of which may have one or more substituents; T represents a single bond, or a C1-3 alkylene group, a C2-3 alkenylene group or a C2-3 alkynylene group, each of which may have one or more substituents; W represents a carboxyl group;- - - represents a single bond etc. ; X represents a single bond, oxygen atom, a group represented by -NRX1CQ1O- (wherein Q1 represents an oxygen atom or sulfur atom; and RX1 represents a hydrogen atom, formyl group, or a C1-6 alkyl group etc., each of which may have one or more substituents), -OCQ1NRX1- (wherein Q1 and RX1 are as defined above), -CQ1NRx1O- (wherein Q1 and RX1 are as def ined above), ONRX1CQ1- (wherein Q1 and RX1 are as defined above), - Q2SO2- (wherein Q2 is an oxygen atom or -NRX10- (wherein RX10 represents a hydrogen atom, formyl group, or a C1-6 alkyl group etc., each of which may have one or more substituents)) or -SO2Q2- (wherein Q2 is as defined above), (wherein, provided that RX2 and RX3, and/or RX4 and RX5 may together form a ring, Q3 and Q4 are the same as or different from each other and each represents an oxygen atom, (O)S(O) or NRX10 (wherein NRX10 is as defined above)); Y represents a 5- to 14-membered aromatic group etc., which may have one or more substituents and one or more hetero atoms; and the ring Z represents a 5-to 14-membered aromatic group which may have 0 to 4 substituents and one or more hetero atoms, and wherein part of the ring may be saturated.
Saccharide accelerated hydrolysis of boronic acid imines
Hartley, James H.,James, Tony D.
, p. 2597 - 2600 (2007/10/03)
Saccharides accelerate the rate of hydrolysis of imines 1 and 2 at pH 7.77. In contrast, the rate of hydrolysis of imine 3 is unaffected by added saccharides.
