Phenothiazine derivatives are described of the formula ##SPC1## In which X.sub.1 and X.sub.2, which may be the same or different, are H, R, F, Cl, Br, OR, CN, --COR, CH.sub.3, --S--R, --SOR, --SO.sub.2 R or --SO.sub.2 N(CH.sub.3).sub.2, where R is an alkyl group having from 1 to 4 carbon atoms, and the quinuclidine ring is substituted by the group --(CH.sub.2).sub.x -- in the 2- or 3- position, x being 1 or 2 when said group is substituted in the 2-position and being 0 or 1 when said group is substituted in the 3-position (because of electronic hindrance), and their acid addition and quaternary ammonium salts, have valuable pharmacological properties. In particular, these compounds have anti-histaminic, anti-cholinergic, adrenolytic, neuro-sedative, tranquillizing and/or spasmolytic properties. These compounds are prepared by condensing an appropriate phenothiazine with a quinuclidine derivative of the formula ##SPC2## In which x has the above-stated meaning and Z is a halogen atom or a reactive ester group.
本发明涉及一种公式为##SPC1##的苯并噻唑衍生物,其中X.sub.1和X.sub.2可以相同或不同,分别为H、R、F、Cl、Br、OR、CN、--COR、CH.sub.3、--S--R、--SOR、--SO.sub.2 R或--SO.sub.2 N(CH.sub.3).sub.2,其中R是具有1至4个碳原子的烷基,且喹诺啉环在2-或3-位被基团--(CH.sub.2).sub.x--取代,当该基团在2-位被取代时,x为1或2,当该基团在3-位被取代时,x为0或1(由于电子阻碍),以及它们的酸加成物和季铵盐,具有有价值的药理作用。特别是,这些化合物具有抗组胺、抗胆碱能、肾上腺神经阻滞、神经镇静、镇静和/或解痉作用。这些化合物是通过将适当的苯并噻唑与公式为##SPC2##的喹诺啉衍生物缩合而制备的,其中x具有上述含义,Z是卤素原子或反应性酯基。
