Animal experiment: | Rats[2]Rats weighing 180 to 190 g are anesthesized with ether and subjected to laparotomy to expose the stomach after which 20 gal of 20% acetic acid is injected carefully under the serous membrane of the abdominal side in the glandular stomach; then the abdomen is closed. Thereafter, the animals are fed normally and 5 mL/kg of BTM-1086 dissolved or suspended in 0.5% gum arabic solution is administered p.o. once daily for 14 days from the second day after the operation. The longitudinal and abscissal length of the areas are quickly measured with a calliper, and the multiplied product is used as the ulcer index[2]. |

BTM-1086 is a potent anti-ulcer and gastric secretory inhibiting agent.
Functional and binding experiments shows that the (-) enantiomer (BTM-1086) has a high affinity (pKi=8.31-9.15) for the three muscarinic receptor subtypes in guinea-pig cortex (M1), heart (M2) and salivary glands (M3)[1].
BTM-1086 prevents the development of ulcer at a dose of 0.1 to 1 mg/kg, p.o., but only weakly inhibits the histamine induced gastric ulcer. The inhibitory activities of BTM-1086 are significantly higher than those of atropine sulfate. In the healing experiment with the acetic acid-induced stomach ulcer, BTM-1086 (1 mg/kg/day , p.o., x14) shows a significant healing effect, which is higher than that of propantheline bromide . BTM-1086 at a dose of 0.2 mg/kg , i.d., remarkably inhibits the gastric secretion 6 hr after pylorus ligation. The aspirin-induced reductions of the total acid and K+ as well as the increments of the volume and Na+ in the gastric secretion are prevented dose-dependently by pretreatment with BTM-1086. The LD50 value by oral, s.c., and i.v. administration with this compound is 880, 630 and 113 mg/kg, respectively, for male rats and 830, 650 and 119 mg/kg, respectively, for female rats[2].

Affinity profiles of BTM-1086 and BTM-1041 at muscarinic receptor subtypes and at H1- and alpha 1-receptors
The affinities of the (+) and (-) enantiomers of the antimuscarinic benzothiazepinone derivative, cis-2,3-dihydro-3-(4-methyl-1-piperazinylmethyl)-2-phenyl-1,5-benzoth iazepin-4 (5H)-one (BTM-1041 and BTM-1086), for muscarinic receptor subtypes, histamine H1-receptors and alpha 1-adrenoceptors were determined in vitro using isolated organs: field-stimulated rabbit vas deferens (M1-receptors), guinea-pig left atrium (M2-receptors), guinea-pig ileum (M3- and histamine H1-receptors) and rat vas deferens (alpha 1-adrenoceptors). We also assessed the binding profile of BTM-1041 and BTM-1086 at muscarinic receptor subtypes in guinea-pig cortex (M1), heart (M2) and salivary glands (M3) as well as at alpha 1-adrenoceptors in rat cerebral cortex. Functional and binding experiments showed that the (-) enantiomer (BTM-1086) had a high affinity (pA2 = 7.98-8.81; pKi = 8.31-9.15) for the three muscarinic receptor subtypes, whereas the (+) enantiomer (BTM-1041) showed a low antimuscarinic potency (pA2 = 4.87-5.31; pKi = 4.85-5.55). This results in an extremely high stereoselectivity for these optical isomers [-)/(+) ratios = 1023 to 6918). The affinity of the (-) enantiomer BTM-1086 was lower for both histamine H1- and alpha 1-receptors than for muscarinic receptors, whereas the reverse was true for the (+) enantiomer, BTM-1041. Thus, the stereochemical demands for the two optical isomers were most stringent at muscarinic receptors but were inverse and less pronounced at histamine H1- and alpha 1-receptors (stereoselectivity ratios = 0.16-0.22).
Antiulcer effect of (-)-cis-2,3-dihydro-3-(4-methylpiperazinylmethyl) -2-phenyl-1,5-benzothiazepin-4-(5H)-one hydrochloride (BTM-1086) in experimental animals
Effects of (-) cis-2,3-dihydro-3-(4-methylpiperazinylmethyl)-2-phenyl-1,5-benz othiazepin-4-(5H ) -one hydrochloride (BTM-1086) on various experimental gastric and duodenal ulcers were studied in rats. In the pylorus-ligated ulcer, restraint and water immersion stress ulcer, and drug-induced ulcer (indomethacin, aspirin, reserpine, serotonin, cysteamine), BTM-1086 prevented the development of ulcer at a dose of 0.1 to 1 mg/kg, p.o., but only weakly inhibited the histamine-induced gastric ulcer. The inhibitory activities of BTM-1086 were significantly higher than those of atropine sulfate. In the healing experiment with the acetic acid-induced stomach ulcer, BTM-1086 (1 mg/kg/day, p.o., X 14) showed a significant healing effect, which was higher than that of propantheline bromide. BTM-1086 at a dose of 0.2 mg/kg, i.d., remarkably inhibited the gastric secretion 6 hr after pylorus ligation. The aspirin-induced reductions of the total acid and K+ as well as the increments of the volume and Na+ in the gastric secretion were prevented dose-dependently by pretreatment with BTM-1086.
In vitro and in vivo antimuscarinic effects of (-)cis 2,3-dihydro-3-(4-methylpiperazinylmethyl)-2-phenyl-1,5 benzothiazepin-4-(5H)one HCl (BTM-1086) in guinea pig peripheral tissues
The potency and selectivity of (-)cis-2,3-dihydro-3-(4-methylpiperazinylmethyl)-2-phenyl-1,5 benzothiazepin-4-(5H)one HCl (BTM-1086) for muscarinic receptor subtypes was compared in functional assay systems, in guinea pig peripheral tissues, to known reference drugs: atropine (nonselective), pirenzepine (M1), AF-DX 116 (M2) and HHSiD (M3). Like atropine, BTM-1086 was a potent, nonselective, competitive muscarinic antagonist with no detectable antispasmodic activity in urinary bladder or ileal muscle. In vivo, in the guinea pig cystometrogram, BTM-1086 depressed intravesical bladder pressure (PvesP) with the same efficacy and potency as oxybutynin, a drug used clinically for the treatment of urinary incontinence. The pharmacological profile of BTM-1086, however, suggests that it may not be suitable for development for bladder dysfunction disorders.
Possible mechanisms of a new type of antispasmodic drug, BTM-1042(cis-(--)-2,3-dihydro-3-(4-methyl-piperazinyl)methyl-2-phenyl-1,5-benzothiazepin-4(5H)-one dihydrochloride)
A newly synthesized compound, BTM-1042 (cis-(--)-2,3-dihydro-3-(4-methyl-piperazinyl)methyl-2-phenyl-1,5-benzothiazepin-4(5H)-one dihydrochloride) depressed the twitch responses of the ileum from guinea pig to electrical stimulation at 0.1 Hz. This inhibitory action of BTM-1042 was not influenced by naloxone, a narcotic antagonist. BTM-1042 proved to be almost as active as atropine on electrically stimulated ileum. BTM-1042 also blocked muscarinic receptors but the potency was about 1/3 of that of atropine. The responses of the ileum of guinea pig to nicotine and 5-hydroxytryptamine also were inhibited by BTM-1042. However, BTM-1042 did not influence the release of transmitters from motor, sympathetic, nonadrenergic inhibitory (or purinergic nerve), noncholinergic excitatory nerves and responses of various smooth muscles mediated through drug receptors, except for the acetylcholine receptor. Spontaneous movement of the unanaesthetized rabbit stomach was dose dependently depressed by BTM-1042 (0.04--0.2 mg/kg, i.v.). The potency ratio for BTM-1042 relative to atropine was 7.4. BTM-1042 is apparently a new type of potent, antispasmodic drug.
