The invention relates to isoxazolidine containing compounds that bind to bcl proteins and inhibit Bcl function. The compounds may be used for treating and modulating disorders associated with hyperproliferation, such as cancer.
An object of the present invention is to provide to a compound and a pharmaceutical composition, which have excellent Syk-inhibitory activity. The present invention provides a nicotinamide derivative represented by the following formula (I) (wherein R
1
represents a halogen atom; R
2
represents a C
1-12
alkyl group, a C
2-12
alkenyl group, a C
2-12
alkynyl group, a C
3-8
cycloalkyl group, an aryl group, an ar-C
1-6
alkyl group or a heterocyclic group, each optionally having at least one substituent; R
3
represents an aryl group or a heterocyclic group each optionally having at least one substituent; and R
4
and R
5
each independently represent a hydrogen atom; and R
2
and R
4
may form a cyclic amino group optionally having at least one substituent together with the nitrogen atom to which they bind) or a salt thereof, and a pharmaceutical composition for use in the treatment of a Syk-related disease which comprises the nicotinamide derivative or a salt thereof.
