Abstract: Pharmaceutical compositions containing 1-(di(hetero)arylmethyl)-3-(substituted amino)-azetidine derivatives (I) are new. Pharmaceutical compositions contain azetidine derivatives of formula (I), or their optical isomers or mineral or organic acid addition salts, as active agents. R1  = NR4R5, N(R4)COR5 or N(R4)S2R6;  R2, R3  = phenyl, naphthyl or indenyl (all optionally substituted (os) by one or more of halo, alkyl, alkoxy, CHO, OH, CF3, OCF3, -CO-alk, CN, COOH, COO-alkyl, CONR7R8, CONHNR9R10, alkylsulfanyl, alkylsulfinyl, alkylsulfonyl, alkylsulfanylalkyl, alkylsulfinylalkyl, alkylsulfonylalkyl, hydroxyalkyl or -alkyl-NR9R10), benzofuryl, benzothiazolyl, benzothienyl, benzoxazolyl, chromanyl, 2,3-dihydrobenzofuryl, 2,3-dihydrobenzothienyl, pyrimidinyl, furyl, imidazolyl, isochromanyl, isoquinolyl, pyrrolyl, pyridyl, quinolyl, 1,2,3,4-tetrahydroisoquinolyl, thiazolyl or thienyl (all os by one or more of halo, alkyl, alkoxy, OH, CF3, OCF3, CN, COOH, COO-alk, CONR7R8, CONHNR9R10, alkylsulfanyl, alkylsulfinyl, alkylsulfonyl, alkylsulfanylalkyl, alkylsulfinylalkyl, alkylsulfonylalkyl, hydroxyalkyl or -alkyl-NR9R10);  R4  = -C(R11)(R12)-Het, Het, -C(R11)(R12)-Ar, Ar, cycloalkyl or norbornyl;  R5  = H, hydroxyalkyl, -alk-COO-alkyl, -alk-CONR7R8, -alk-NR7R8, alkoxy, Ar, Het, CH2Ar, CH2Ar or alkyl (os by one or more halo);  R6  = as R5 but not H;  R7, R8  = H or alkyl;  or NR7R8  = 3-10 membered saturated mono- or bicyclic heterocycle, optionally containing another O, S or N heteroatom and os by one or more alkyl;  R9, R10  = H, alkyl, COO-alk, cycloalkyl, alkylcycloalkyl, -alk-O-alk or hydroxyalkyl;  or NR9R10  = 3-10 membered saturated mono- or bicyclic heterocycle, optionally containing another O, S or N heteroatom and os by one or more of alkyl, -CO-alk, -COO-alk, -CONH-alk, -CSNH-alk, oxo, hydroxyalkyl, -alk-O-alk or CONH2;  R11  = H, hydroxyalkyl, -alk-COO-alkyl, -alk-CONR7R8, -alk-NR7R8, alkoxyalkyl, Ar, Het, CH2Ar, CH2Ar or alkyl (os by one or more halo);  R12  = as R11 but not H;  or CR11R12  = 3-10 membered saturated mono- or bicyclic ring system, optionally containing an O, S or N heteroatom and os by one or more alkyl;  Ar  = phenyl, naphthyl or indenyl (all os by one or more of halo, alkyl, alkoxy, -CO-alk, CN, COOH, COO-alk, CONR7R8, CONHNR7R8, alkylsulfanyl, alkylsulfinyl, alkylsulfonyl, -alk-NR7R8, NR7R8, alkylthioalkyl, CHO, OH, hydroxyalkyl, Het, -O-alk-NH-cycloalkyl, OCF3, CF3, -NHCO-alk, SO2NH2, NHCOMe, NHCOO-alk, Het or OCH2O (linked to two adjacent C));  Het  = 3-10 membered saturated or unsaturated mono- or bicyclic heterocycle, containing one or more O, S or N heteroatom(s) and os by one or more alkyl, alkoxy, halo, alkoxycarbonyl, oxo or OH (N-containing heterocycles optionally being in N-oxide form);  alk  = alkyl or alkylene;  Alkyl or alkylene moieties have 1-6C and cycloalkyl moieties have 3-10C. Independent claims are also included for: (1) (I) (including optical isomers and salts) as new compounds, with the exception of (I; R1 = N(Ph)SO2Me; R2, R3 = Ph); and (2) the preparation of the new compounds (I).
