INTRODUCTION Oxybutynin and tolterodine are two drugs widely used for the management of overactive bladder and urge urinary incontinence. The once-daily, extended-release formulations benefit from being well tolerated and efficacious. However, their costs, compared with generic immediate-release (IR) oxybutynin, are significantly greater. This study compared the cost effectiveness of oxybutynin...

The title compound, C(16)H(12)O(5)S, was prepared by oxidation of 2-methyl-5,6-methyl-ene-di-oxy-3-phenyl-sulfanyl-1-benzo-furan with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 83.64 (4)° with the mean plane of the 5,6-(methyl-ene-di-oxy)-benzo-furan fragment. The crystal structure is stabilized by C-H⋯π inter-actions between a benzene H atom of the 5,6-(methyl-ene-...

In the title mol-ecule, C(21)H(19)N(3)O(2), the central pyridine ring makes dihedral angles of 14.46 (9) and 34.67 (8)° with the 4-amino- and 4-eth-oxy-substituted benzene rings, respectively. The eth-oxy group is essentially coplanar with the attached benzene ring [C-O-C-C torsion angle = 178.70 (16)°] as is the meth-oxy group with the pyridine ring [C-O-C-N torsion angle = -3.0 (3)°]. In the ...

Three coumarin-derived fluorescent probes, 3-acetyl-7-[(6-bromohexyl)oxy]-2H-chromen-2-one (FM1), 7-[(6-bromohexyl)oxy]-4-methyl-2H-chromen-2-one (FM2) and ethyl 2-{7-[(6-bromohexyl)oxy]-2-oxo-2H-chromen-4-yl}acetate (FM3), are described, with their photophysical constants. The compounds were tested in preliminary studies employing epifluorescence microscopy demonstrating that they allow the im...

The title compound, C20H23N3O6·CH3OH, was synthesized by [3 + 2] cyclo-addition of (Z)-2,3-bis-(3,4,5-tri-meth-oxy-phen-yl)acrylo-nitrile with sodium azide and ammonium chloride in DMF/water. The central nitro-gen of the triazole ring is protonated. The dihedral angles between the triazole ring and the 3,4,5-tri-meth-oxy-phenyl ring planes are 34.31 (4) and 45.03 (5)°, while that between the 3,...

In the title compound, C(11)H(19)NO(5), the five-membered pyrrolidine ring adopts an envelope conformation. The dihedral angles between the carboxyl group plane, the pyrrolidine ring and the meth-oxy group are 59.50 (3) and 62.02 (1)°, respectively. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains along [100]. The absolute configuration is assigned in accord ...

The title compound, C(15)H(13)Br(4)NO(4), was obtained via radical bromination reaction of ethyl 6,7-dimeth-oxy-2-methyl-quinoline-3-carboxyl-ate and N-bromo-succinimide (NBS) in the presence of benzoyl peroxide (BPO) under photocatalytic conditions. The quinoline ring system is approximately planar with a maximum deviation from the mean plane of 0.035 (1) Å. The dihedral angle between the six-...

In the title compound, C20H17NO, the dihedral angle between the mean planes of the 4-meth-oxy-phenyl ring and the naphthalene ring is 69.50 (7)°. The meth-oxy group is almost coplanar with the benzene ring to which it is connected [Cb-Cb-Om-Cm torsion angle of -7.9 (2)°; b = benzene and m = meth-oxy] and the imine group displays a C-C-N=C torsion angle is -57.2 (2)°. The imine (C=N) group has a...

In the title compound, C17H18O5, the dihedral angle between the benzene rings is 31.23 (16)°. In the crystal, the mol-ecules are packed in an anti-parallel fashion in layers along the a axis. In each layer, very weak C-H⋯O hydrogen bonds occur between the meth-oxy and methyl ester groups. Weak C-H⋯π inter-actions between the 4'- and 5'-meth-oxy groups and neighbouring benzene rings [meth-oxy-C-...
