Substitute for 'is' with types of object known in runtime

I'm trying to check if some Typeis instance of another Type. Like in this simple method, the best option would be:

bool Example(Type instance, Type runtimeKnwownType) {
    return instance is runtimeKnwownType;
}

It is the best option because is works with interfaces, however it doesn't work with Type and not constant right operand. Another option is Type.IsSubclassOf(object) doesn't work with interfaces. So there is my question for substition of is in this scenario.
