Recent studies have shown that many types of mushrooms may have important physiological functions in humans including antioxidant activities, regulation of blood lipid level and blood glucose level. The present study was designed to investigate the antihyperglycemic effect of ethanolic Terfezia boudieri Chatin (TBC) extract on streptozotocin (STZ) induced-diabetic rats. The results showed that, rats which were fed with a concentration of 200mg/kg of TBC ethanolic extract had a significant reduction in the plasma blood glucose (P<0.005). Polydipsia was stronger in the induced diabetic rats which were not fed with TBC extract than in those receiving the T. boudieri extract.

Abstract: In this study, target compounds 5–12 were synthesized via acid amine coupling of ibuprofen and naproxen with methyl ester derivatives of amino acids, namely, l-proline, sarcosine, l-tyrosine, and l-glutamic acid. When tested for anti-inflammatory activity using the acute carrageenan-induced hind paw method in rats, compounds 5–12 showed significantly greater anti-inflammatory activity, in the range of 40.64%–87.82%, compared with a placebo control group (P , 0.001). Among the newly synthesized compounds 5–12, naproxen derivatives 9–12 with anti-inflammatory activity ranging between 66.99% and 87.82% showed significantly higher (P , 0.05) potency than ibuprofen derivatives 5–8 with inhibition in the range of 22.03%–52.91% and control groups of ibuprofen (76.34%) or naproxen (75.59%, P , 0.05). Moreover, derivatives 9–12 derived from naproxen, in particular compounds 9 and 10 which achieved 83.91% and 87.82% inhibition of inflammation, respectively, showed significantly (P , 0.05) higher potency than naproxen derivatives 11 and 12. Notably, among naproxen derivatives 9–12, the gastric ulcerogenicity for 9 (ulcer index 11.73) and 10 (ulcer index 12.30) was found to be significantly lower (P , 0.05) than that of the active ibuprofen and naproxen control groups with ulcer indices of 22.87 and 24.13, respectively. On the other hand, naproxen derivatives 9–11 showed significant inhibition (P , 0.05) of prostaglandin E2 synthesis when compared with the active control group receiving indomethacin, suggesting a correlation between the observed low ulcerogenicity and effect on prostaglandin E2 synthesis for compounds 9 and 10. However, significant inhibition of prostaglandin E2 observed for naproxen derivative 11 (107.51) did not correlate with its observed ulcer index (16.84). Our overall findings for carbamoylmethyl ester derivatives named 5–12 clearly suggest that the compounds showing potent antiinflammatory effect.

The aim of this study was to identify nationals at risk of developing type 2 diabetes within the next 10 years in some areas across Tripoli Health Authority in Libya. In this questionnaire-based survey, a total of 400 Libyan nationals of both genders were randomly selected from seven areas across the central area of Tripoli Health Authority (Soug El-Juma, Zawet Dahmani, Al-Furnaj, Ain Zara, Al-Madena Centre, Al-Dhahra Centre, and Noflean). All participants approached (400) completed the study and responded to the items of the survey. Based on a modified Finnish Type 2 Diabetes Risk Score test (FINDRISC), 129 (32.3%) were categorised as either at moderate or at high/very high risk of developing diabetes within the next 10 years of life. Among the 129 participants at risk, body mass index was >25kg/m2 in 125 (96.9%) and waist circumferences were high (>88cm for females; >102cm for males) in almost 45% of the women and 22% of the men. We found that in the sample studied the risk of developing diabetes was clear, and there is no doubt that interventions to reduce such risk are a priority rather than a need. Diabetes has a great impact on the health of the nation and also on the future resources of the country in managing the disease and its complications; a health education/health campaign could be one good answer to tackle the problem.

Synthesis of 5-hydroxy-2,3,4,5-tetrahydro-[1H]-2-benzazepin-4-ones: Selective antagonists of muscarinic (M3) receptors

Two approaches to tetrahydro-[1H]-2-benzazepin-4-ones of interest as potentially selective, muscarinic (M(3)) receptor antagonists have been developed. Base promoted addition of 2-(tert-butoxycarbonylamino)methyl-1,3-dithiane with 2-(tert-butyldimethylsiloxymethyl)benzyl chloride gave the corresponding 2,2-dialkylated 1,3-dithiane which was taken through to the dithiane derivative of the parent 2,3,4,5-tetrahydro-[1H]-2-benzazepin-4-one by desilylation, oxidation and cyclisation via a reductive amination. After conversion into the N-tert-butyloxycarbonyl, N-toluene p-sulfonyl and N-benzyl derivatives , hydrolysis of the dithiane gave the N-protected tetrahydro-[1H]-2-benzazepin-4-ones . However, preliminary attempts to convert these into 5-cycloalkyl-5-hydroxy derivatives were not successful. In the second approach, ring-closing metathesis was used to prepare 2,3-dihydro-[1H]-2-benzazepines which were hydroxylated and oxidized to give the required 5-hydroxy-2,3,4,5-tetrahydro-[1H]-2-benzazepin-4-ones. Following preliminary studies, ring-closing metathesis of the dienyl N-(2-nitrophenyl)sulfonamide gave the dihydrobenzazepine which was converted into the 2-butyl-5-cyclobutyl-5-hydroxytetrahydrobenzazepin-4-one by hydroxylation and N-deprotection followed by N-alkylation via reductive amination, and oxidation. This chemistry was then used to prepare the 2-[(N-arylmethyl)aminoalkyl analogues , , and . N-Acylation followed by amide reduction using the borane-tetrahydrofuran complex was also used to achieve N-alkylation of dihydrobenzazepines and this approach was used to prepare the 5-cyclopentyl-5-hydroxy-2,3,4,5-tetrahydro-[1H]-2-benzazepin-4-one and the 5-cyclobutyl-8-fluoro-5-hydroxy-2,3,4,5-tetrahydro-[1H]-2-benzazepin-4-one . The structures of 2-tert-butyloxycarbonyl-4,4-propylenedithio-2,3,4,5-tetrahydro-[1H]-2-benzazepine and (4RS,5SR)-2-butyl-5-cyclobutyl-4,5-dihydroxy-2,3,4,5-tetrahydro-[1H]-2-benzazepine were confirmed by X-ray diffraction. The racemic 5-cycloalkyl-5-hydroxy-2,3,4,5-tetrahydro-[1H]-2-benzazepin-4-ones were screened for muscarinic receptor antagonism. For M(3) receptors from guinea pig ileum, these compounds had log(10)K(B) values of up to 7.2 with selectivities over M(2) receptors from guinea pig left atria of approximately 40.

Investigation of the mechanism for the relaxation of rat duodenum mediated via M1 muscarinic receptors

Published in: Autonomic & Autacoid Pharmacology 26(3):275-84

1 Relaxation responses of the rat isolated duodenum to the putative M1 muscarinic receptor agonist, McN-A-343, were examined to determine whether the response was due to the release of known non-adrenergic, non-cholinergic relaxant neurotransmitters and to establish the involvement of M1 muscarinic receptors. 2 The role of ATP was examined with the P2 receptor antagonist, suramin, which at 30 μm antagonized the relaxant responses to α,β-methylene ATP. The same dose, however, failed to inhibit the relaxation by McN-A-343. 3 The role of nitric oxide (NO) was examined with the NO synthase inhibitor, NG-nitro-l-arginine methyl ester (l-NAME; 100 μm), which failed to inhibit the responses to McN-A-343. As NO mediates relaxation of the duodenum via cGMP generation through guanylyl cyclase, whether the relaxation by McN-A-343 was also via cGMP was examined with the guanylyl cyclase inhibitor, 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ). The relaxation responses to the NO donor, S-nitroso-N-acetyl penicillamine, were inhibited in the presence of ODQ (3 μm), but not those by McN-A-343. 4 Release of γ-aminobutyric acid (GABA) was examined with the GABAA receptor antagonist, bicuculline (10 μm), which shifted the concentration–response curves for the relaxation of the duodenum by GABA to the right. There was a similar degree of shift in the concentration–response curve for McN-A-343 by bicuculline indicating that release of GABA from enteric neurones of the duodenum could explain the relaxation response to McN-A-343. 5 To test whether the muscarinic receptors mediating the relaxation of the duodenum were of the M1 subtype, the susceptibility to the selective competitive antagonist, pirenzepine and the selective muscarinic toxin from green mamba, MT7, was examined. Pirenzepine (1 μm) shifted the concentration–response for McN-A-343 to the right in a parallel fashion with a dose ratio of 33.3 ± 20.2. This yielded a pA2 value of 7.5, which concords with those for other responses reputed to be mediated via M1 muscarinic receptors. The toxin MT7 was used as an irreversible antagonist and following incubation with the duodenum was washed from the bath. An incubation time of 30 min with 100 nm of MT7 caused a significant parallel shift in the concentration–response to McN-A-343 confirming the involvement of M1 muscarinic receptors. 6 This study has confirmed that McN-A-343 relaxes the rat duodenum via muscarinic receptors of the M1 subtype and that these receptors are probably located on enteric neurones from which their stimulation releases GABA.
