Tricyclic derivatives of formula (1), wherein R1 may be an alkyl sulphonate or sulphonamide group, are useful as antimicrobial agents. The derivatives are optionally substituted wherein R2 is a hydrogen, a halogen, a substituted alkyl group, a thioether or an acetyl group; Y may be N, or C; X may be S, SO, SO2, N, O, CH2, C(O), CO2, NHCO, and ring B is a 6, 7 or an 8 membered cycloalkyl ring. The tricyclic derivatives, such as phenothiazine derivatives, may be used in treating tuberculosis, especially drug sensitive and resistant forms of tuberculosis. The derivatives of the invention may be used independently or in combination with known anti-tubercular drugs such as isoniazid, ethionamide and ethambutol, and the combination may be administered as a single dose, or as two independent dosages. The tricyclic derivatives may also be used for the manufacture of a medicament for treating tuberculosis.
