摘要:
Compounds of Formula I have been shown to enhance the release of the neurotransmitter acetylcholine, and thus may be useful in the treatment of diseases of man, such as in Alzheimer's disease and other conditions involving learning and cognition, where subnormal levels of this neurochemical are found. The compounds of this invention can be described as shown in Formula I ##STR1## where Q is ##STR2## R.sup.1 is 4-, 3-, or 2-pyridyl, pyrimidyl, pyrazinyl, or fluoro-4-pyridyl; R.sup.2 and R.sup.3 are independently H, F, Cl, Br, NO.sub.2, OH, --R.sup.4, --O--R.sup.4, --CO.sub.2 R.sup.4, --COR.sup.4, --CONH.sub.2, --CONHR.sup.4, --CONR.sub.4 R.sup.4', --S(O).sub.m2 --R.sup.4, NH.sub.2, CF.sub.3, NHR.sup.4, NR.sup.4 R.sup.4' ; R.sup.4 and R.sup.4' are independently H, alkyl of 1 to 4 carbons, CH.sub.2 Phe-W or Phe-W; Phe is a phenyl group; R.sup.5 is --(CH.sub.2).sub.n --Y or --OCOR.sup.4 ; Y is H, OH, NH.sub.2, NHR.sup.4, NR.sup.4 R.sup.4', NHCOR.sup.4, NHCO.sub.2 R.sup.4, NHS(O).sub.2 R.sup.4 ; F, Cl, Br, OR.sup.4, S(O).sub.m R.sup.4, --CO.sub.2 H, --CO.sub.2 R.sup.4, --CN, --CONR.sup.4 R.sup.4', --CONHR.sup.4, --CONH.sub.2, --COR.sup.4 ; --CH.dbd.CHCO.sub.2 R.sup.4, --OCOR.sup.4, Phe, Phe--W, --C.tbd.CCO.sub.2 R.sup.4, --CH.dbd.CHR.sup.4, or --C.dbd.C--R.sup.4 ; W is F, Cl, Br, R.sup.4, OR.sup.4, NO.sub.2, NH.sub.2, NHR.sup.4, NR.sup.4 R.sup.4, CN, S(O).sub.m --R.sup.4 ; m is 0, 1 or 2; n is 1 to 7; and hydrates and physiologically suitable salts thereof.

摘要:
Compounds which block neuronal M-channels are useful for treating conditions involving neurotransmitter deficiencies, traumatic brain injury, or the depressive phase of bipolar disorder. Compounds can be evaluated for utility in treating these conditions by determining whether they are capable of blocking neuronal M-channels.
