We report here2 cases of patients with Sjögren’s syndrome with dry mouth that were successfully treated with cevimeline hydrochloride. The first case was diagnosed as Sjogren’s syndrome at our clinic, and the saliva secretion increased by more than three-fold following oral cevemeline hydrochloride. The second case was diagnosed at another hospital, and the saliva secretion was increased by mor...

feat, it seemed reasonable to assume that accessibility and distribution of abortion services in Canada would increase because all independent health care facilities could now offer the procedure without criminal penalties. However, while decriminalization and regulation under the Health Act gave abortion the same status as other medical procedures, controversy over its existence and its delive...

Since a safe and effective mass vaccination program against dengue fever is not presently available, a good way to prevent and control dengue outbreaks depends mainly on controlling the mosquito vectors. Aedes aegypti mosquito populations can be monitored and reduced by using ovitraps baited with organic infusions. A series of laboratory experiments were conducted which demonstrated that the ba...

In the title mol-ecule, C(25)H(19)N(3)O(3)S(3), the tetra-hydro-pyridine ring adopts a half-chair conformation. The dihedral angle between the least-squares plane through the tetra-hydro-pyridine ring and two thio-phene and two benzene rings are 6.25 (9), 89.49 (9), 76.43 (9) and 84.93 (8)°, respectively, while the dihedral angle between the 1,3,4-oxadiazole and tetra-hydro-pyridine rings is 81...

In the title compound, C(28)H(24)F(2)N(2)O(6)S, the whole mol-ecule is disordered over two sites with refined occupancies of 0.778 (3) and 0.222 (3). The central benzene ring makes dihedral angles of 56.0 (4), 34.5 (4) and 70.9 (4)°, respectively, with the two terminal benzene rings and the 1,3,4-oxadiazole ring in the major component of the disordered mol-ecule. The corresponding angles in the...

Apart from carbon atoms, some cyclic molecules contain other elements and play an extraordinary role in human life. Among these systems, 1,3,4-oxadiazole derivatives deserve special attention due to their biological properties such as antibacterial, antifungal, antitumor, anti-inflammatory properties. They are commonly used pharmacology, well fungicidal, herbicidal, insecticidal agricultural ap...

Parasitic flatworms cause serious infectious diseases that affect humans and livestock in vast regions of the world, yet there are few effective drugs to treat them. Thioredoxin glutathione reductase (TGR) is an essential enzyme for redox homeostasis in flatworm parasites and a promising pharmacological target. We purified to homogeneity and characterized the TGR from the tapeworm Mesocestoides...

The title compound, C(14)H(8)N(4)O(6), a new 1,2,5-oxadiazole N-oxide derivative, was formed by dimerization of 4-nitro-benz-al-de-hyde oxime. The compound crystallizes with two independent mol-ecules per asymmetric unit. The N-oxide O atom is disordered over two sites in each mol-ecule; site occupancy factors are 0.57/0.43 and 0.5/0.5. The mean planes through the two benzene rings are inclined...

Metabolites of a G protein-coupled receptor modulator containing 1,2,4-oxadiazole and piperazine substructures were identified in vitro in human, rat, and dog hepatocyte incubates and in vivo in rat plasma, bile, urine, and feces by using 14C-radiolabeled parent compound. Exposure coverage for the major circulating metabolites in humans at steady state and in preclinical species used in drug sa...

A series of 3,4-diaryl-1,2,5-oxadiazoles and 3,4-diaryl-1,2,5-oxadiazole N-oxides were prepared and evaluated for COX-2 and COX-1 binding affinity in vitro and for antiinflammatory activity by the rat paw edema method. p-Methoxy (p-OMe) substituted compounds 9, 21, 34, 41, 42 showed COX-2 enzyme inhibition higher than that showed by compounds with other substituents. 3,4-Di(4-methoxyphenyl)-1,2...
