Abstract: This paper is concerned with certain generalized subclasses of bi-univalent functions defined with subordination in the open unit disc $E=\left\rbrace z:\mid z \mid <1\right\lbrace $. The bounds for the initial coefficients for the functions in these classes are studied. The earlier known results follow as special cases.
