similar reaction employing 2-cyano-4-indolyl glycidyl ether yielded the respective cyano derivatives 10 and 11. Apparent affinities (Ki, M) for beta-adrenoceptors on membrane preparations from rat heart and lung were 4.6 X 10(-10) and 1.34 X 10(-9) for 8, 2.3 X 10(-8) and 4.5 X 10(-9) for 9, 6.1 X 10(-10) and 1.49 X 10(-9) for 10, and 1.83 X 10(-9) and 2.78 X 10(-9) for 11, respectively.
