The invention is useful in seizure treatment.

Notably, the present invention provides a further method for ameliorating such a siezure as aforesaid. The treatment it provides can be unexpectedly effective.

Further advantages attend this invention as well.

ILLUSTRATIVE DETAIL

The terms "ameliorating" or "ameliorate" refer herein to improving or improvement by reduction or termination of the seizure condition of the mammal. It refers to all degrees of improvement, also including prevention.

The term "generalized tonic-clonic type epileptic seizure" refers herein to the usual or composite form especially denoting a symptom complex characteristic of a class or the like of a bilaterally symmetrical convulsion, without local onset, of a tonoclonic, i.e., of both a tonic and a clonic, nature, which is a state of continuous, unremitting muscular contraction followed by repetitive contraction and relaxation, i.e., jerking, symptiomatic of a chronic disorder characterized by paroxysmal attacks of brain dysfunction due to excessive neuronal discharge, and usually associated with some alteration of consciousness. However, as such, the term is intended to represent a diagnosis classification approved by the International League Against Epilepsy in September of 1981. See e.g., Porter et al., Cleve. Clin. Q., 51 293-305 (1984).

The term "systemically administering" refers herein to applying or giving to the organism entirely as distinguished from any of its individual parts. As such, systemically administering of the Benzothiazepine-compound can be generally accomplished by such methods as, for example, oral ingestion of an oral or sublingual dosage form such as a tablet, capsule, bead sample, syrup, elixer, dragee, and so forth and the like, injection of an injectable solution or suspension, application of a transdermal or other external preparation such as a solution, creme, gel or other ointment, and/or insertion of a rapid or sustained release device.

The term "mammal"refers herein to an animal of the class Mammalia. The mammal can be a human being.

The term "need of treatment therefor" refers herein to a condition requiring management or relief for the generalized tonic-clonic type epileptic seizure included are posterior, prohpylactic and/or palliative treatment(s).

The term "Benzothiazepine-compound" refers herein to a benzothiazepine-type compound, and to pharmaceutically acceptable salt(s) thereof, having calcium antagonist activity and which is represented by the following general formula: ##STR2## wherein Q is hydro (H) or halo to include fluoro (F) and chloro (Cl), especially H or 8-Cl;

R is H, lower alkoxy, lower haloalkyl, cyano (CN), lower alkyl to include methyl (CH3) or halo to include F & Cl, especially H, methoxy (OMe), trifluoromethyl (CF3) or CN; Y is OR', wherein R' is H or alkylacyl to include, e.g., lower alkylacyl and adamantylcarboxy, etc., especially H, or lower alkylacyl to include groups such as acetyl, propionyl, butyryl, pivalyl, valeryl, isovaleryl, etc., provided that then there is full saturation between carbons 2 & 3 of the benzothiazepine nucleus and 2,3-dihydro-functionality thereat as well, or Cl, provided that then there is ethylenic unsaturation between positions 2 & 3 of the benzothiazepine nucleus, and R"is 2-[di(lower alkyl)amino]ethyl (R"1), 3-[di(lower alkyl)amino]propyl (R"2), 2-(pyrrolidino)ethyl (R"3), 3-(pyrrolidino)propyl (R"4), 2-piperidino)ethyl (R"5), 3-(piperidino)propyl (R"6), 2-(morpholino)ethyl (R"7), 3-(morpholino)propyl (R"8) or (N-pyridinium)alkyl with a suitable counterion being present (+R"9-X), especially R"1, e.g., with R"1 being 2-(dimethylamino)ethyl (R"1a) or with R"1 being 2-(diisopropylamino)ethyl (R"1b), or R"3, or R"5, or +R"9-X, e.g., with +R"9-X being 2-(N-pyridinium)ethyl with a bromide and/or chloride counterion being present (+R"9a-X), provided that, in the cis-configuration, when Q is H or 8-Cl, R is methoxy, R' is acetyl, and R" is R"1a, the compound is the levorotary isomer.

Generally, with respect to the 2,3-dihydro compounds, the cis-configuration, i.e., about positions 2 & 3 of the benzothiazepine nucleus, is or can be present, with some exceptions to this, e.g., as aforesaid and also preferably 7 with the trans-configuration, i.e., about positions 2 & 3 of the benzothiazepine nucleus, being present in the cases of Q being H or 8-Cl, R being methoxy, R' being H, and R"being R"5. Also generally, if the compound has a chiral carbon, racemates or separate optical antipodes may be present in the practice of this invention, with some exceptions to this, e.g., the levorotary optical antipodes corresponding to diltiazem and to d-cis-TA3090 being two such exceptions.

Suitable pharmaceutically acceptable salts generally sulfate, the citrate, and so forth.

The Benzothiazepine-compounds can be made by reacting a suitable glycidic acid ester with a suitable aminothiophenol to prepare corresponding aminophenylthiopropionic acid ester, then cyclyzing the latter ester or its corresponding free acid, followed by N-alkylation and 3-acylation as may be desired. See e.g., Kugita et al., U.S. Pat. No. 3,562,257 (Feb. 9, 1971); Takeda et al., U.S. Pat. No. 4,567,175 (Jan. 28, 1986); Borcherding et al., U.S. patent application Ser.

In addition, the Benzothiazepine-compounds having the vinyl chloride at positions 2 & 3 of the benzothiazepine nucleus can be made by processes known in the art. See e.g., Krapcho et al., U.S. Pat. No. 3,895,006 (Jul. 15, 1975); Krapcho et al., U.S. Pat. No. 3,983,106 (Sept. 28, 1976); Krapcho, U.S. Pat. No. 3,075,967 (Jan. 29, 1963), each of these being incorporated herein by reference.

The term "an amount effective" refers herein to an effective amount, which is any amount necessary to at least ameliorate, or optimally completely control or prevent, the seizures. For example, in human patients in general, effective amounts can be about from 0.1 to 300 mg of Benzothiazepine-compound administered per day.

The following further illustrates this invention.

EXAMPLE

All compounds were dissolved in deionized water and administered at a dose from 0.1 milligram (mg) per kilogram (kg) of mammal weight to 100 to 300 mg per kg of mammal weight. Each sample, or control, was administered by interperitoneal injection in a volume of liquid equal to 10 microliters (uL) of the liquid per g of mammal weight. Each mammal was a male CF-1 mouse (Charles Rivers Breeding Laboratories) weighing an average of 25 g. One hour after the injection, the mouse was tested. In general, rotorod toxicity (RT), maximal electroshock seizure (MES) and subcutaneous pentylenetetrazole seizure threshold (scMET) tests were carried out, without administration of anesthesia as anesthetic agents may have interfered with seizure development and therefore masked any beneficial actions of the administered compounds, as follows.

The RT test, designed to detect a minimal neurological deficit from acute compound-induced toxicity in the mouse, required that the mouse was placed on a 1-inch (2.54 cm) diameter knurled plastic rod rotating at 6 rotations per minute (rpm). Neurological deficit, e.g., ataxia, sedation, hyperexcitability, was indicated by the inability of a mouse to maintain equilibrium on the rotating rod for at least 1 minute in each of 3 trials, normal mice able to remain indefinitely on the rotating rod.

Data from the RT test was used to calculate, by probit analysis, the dose at which 50 percent of mice would fail the RT test. This was considered a toxic dose for half of a sample of mice, i.e., TD50, in dose units, i.e., in units of mg per kg.

The MES test, designed to elicit maximal seizure in all normal mice, required that a 60 Hertz (Hz) alternating current (AC) of 50 milliamperes (mA), 5 to 7 times that necessary to elicit minimal seizure, was delivered by 10 corneal electrodes for 0.2 seconds. A drop of 0.9 weight percent aqueous sodium chloride solution was applied to each eye of the mouse, and the electrical stimulus was applied. The mouse was restrained by hand and released at the time of stimulation in order to visually observe the entire seizure, which typically lasted for approximately 22 seconds and was characterized by a short period of initial tonic flexion followed by a prolonged period of tonic extension, especially of the hind legs, and finally a short period of terminal clonus. Elimination of the hind-leg tonic-extensor component, i.e., hind-leg tonic extension that did not exceed a right angle to the trunk of the body, indicated that the compound can prevent MES-induced seizure spread, and therefore, failure of the mouse to extend its hind limbs to an angle with the trunk of the body greater than the right angle was defined as protection.

Data from the MES test was used to calculate, by probit analysis, the dose at which 50 percent of mice would be protected in the MES test. This was considered an effective dose for half of a sample of mice, i.e., ED50, in dose units, i.e., in units of mg per kg.

A therapeutic index (TI) can be calculated by dividing the TD50 by the ED50. The TI is indicative of a margin of safety of a drug such that the higher the TI of a drug, the safer it is.

The scMET test, designed to produce threshold or minimal (olonio) seizures, required the subcutaneous administration of METRAZOL, as a solution of 0.85 weight percent METRAZOL in 0.9 weight percent aqueous sodium chloride solution, in a loose fold of skin on the back of the neck of the mouse in a dose of 85 mg per kg. The mouse was observed for seizures for 30 minutes after the METRAZOL administration, during which time characteristic clonic seizures are produced in approximately 98 percent of normal mice. The absence of a single 5 second episode of clonic spasms, a threshold seizure, was defined as protection.

Table I identifies compounds tested, with substituent references being made to the formula I. Note that the compounds are specifically identified in terms of particular isomers or configurations. However, analogous compound nomenclature without such specific identification refers to all isomeric homologs of that compound. Table II lists results, with dose units being mg per kg.
