Delineation of the Role of Astroglial GABA Transporters in Seizure Control

Studies of GABA transport in neurons and astrocytes have provided evidence that termination of GABA as neurotransmitter is brought about primarily by active transport into the presynaptic, GABAergic nerve endings. There is, however, a considerable transport capacity in the astrocytes surrounding the synaptic terminals, a transport which may limit the availability of transmitter GABA leading to a higher probability of seizure activity governed by the balance of excitatory and inhibitory neurotransmission. Based on this it was hypothesized that selective inhibition of astrocytic GABA transport might prevent such seizure activity. A series of GABA analogs of restricted conformation were synthesized and in a number of collaborative investigations between Prof. Steve White at the University of Utah and medicinal chemists and pharmacologists at the School of Pharmacy and the University of Copenhagen, Denmark, GABA analogs with exactly this pharmacological property were identified. The most important analogs identified were N-methyl-exo-THPO (N-methyl-3-hydroxy-4-amino-4,5,6,7-tetrahydro-1,2-benzisoxazole) and its lipophilic analog EF-1502 ((RS)-4-[N-[1,1-bis(3-methyl-2-thienyl)but-1-en-4-yl]-N-methylamino]-4,5,6,7-tetrahydrobenzo[d]isoxazol-3-ol) both of which turned out to be potent anticonvulsants in animal models of epilepsy.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 503-74-2, you can contact me at any time and look forward to more communication. Recommanded Product: 3-Methylbutanoic acid.

Death following an intramuscular injection of paliperidone: A case report

Paliperidone (9-hydroxyrisperidone), the primary active metabolite of risperidone, is a benzisoxazole derivative of the second-generation antipsychotics. Paliperidone patmitate or PP (the patmitate ester of paliperidone) is available as a once-daily oral tablet, a once-monthly injection or PP1M, and a 3-monthly injection or PP3M (marketed under the name of Trevicta (R) in the European Union). Despite the recent availability of PP3M, several cases of intoxication have been reported worldwide, including lethal cases. However, in Europe, no case of fatal poising has been reported to date. A 33-year-old man was found dead in his room at his parents’ home. His only medical background was a history of schizophrenia. The external examination was without any particularity except a runny nose of brownish liquid with an alcoholic smell. Given the context and the tack of evidence of a third party intervention, an autopsy was not considered necessary. Toxicological analysis of right femoral blood highlighted the presence of paliperidone (240 mu g/ L) only. The risk associated with the use of PP3M formulation is still imperfectly evaluated and several cases of intoxication have been reported worldwide, including fatal cases. In this case, paliperidone poisoning appears to be the highly likely cause of death. In fact, the blood concentration of paliperidone is high, twice the toxicity threshold used in therapeutic monitoring, and no other substances have been identified. This case highlights: the necessity to always evaluate the benefit-risk balance when prescribing this sustained-release form of paliperidone and the difficulties in interpreting paliperidone concentration in forensic cases.

SYNTHESIS AND CATALYTIC PROPERTIES OF HYDROPHOBICALLY-MODIFIED POLY(ALKYLMETHYLDIALLYLAMMONIUM CHLORIDES)

Novel non-cross-linked and cross-linked, hydrophobically modified homo- and copolymers were synthesized by free-radical cyclo(co)polymerization of alkylmethyldiallylammonium chloride monomers in aqueous solution using ammonium persulfate as the initiator. Cross-linking was brought about by addition of a small amount of N,N’-methylenebisacrylamide. The cross-linked homo- and copolymers showed an increase of their reduced viscosity in aqueous solution upon the controlled introduction of cross-linking agent into their chemical structure. Viscosity measurements revealed that the conformational transition of polysoaps to compact coils in aqueous solution is strongly dependent upon the hydrophobic group content of the polysoaps. The formation of hydrophobic microdomains is akin to intramolecular micelle formation. Depending on the hydrophobic group content and the percentage of cross-linking, intermolecular aggregation was also revealed by viscosity measurements at higher concentrations of polysoap. The hydrophobic microdomains of the non-cross-linked and cross-linked polysoaps were characterized by hypsochromic shifts of the long-wavelength absorption band of Methyl Orange as a solvatochromic probe, non-covalently bound to the macromolecule. Catalysis of the unimolecular decarboxylation of 6-nitrobenzisoxazole-3-carboxylate by the non-cross-linked and crosslinked copolymers was investigated in aqueous solution at pH 11.3 and 30 degrees C. The cross-linked polysoaps exhibited higher catalytic activities for decarboxylation than the corresponding non-cross-linked analogues. A maximum in rate constant was found at about 0.2% (w/w) of cross-linking agent in the cross-linked polysoaps. The decarboxylation rate is strongly dependent upon the hydrophobic group content in the polysoaps.

Research and development of zonisamide, a new type of antiepileptic drug

Zonisamide (1,2-benzisoxazole-3-methanesulfonamide, AD-810) is a broad spectrum antiepileptic drug which has been launched in Japan and South Korea. It lacks the ureide structure included in most of the existing antiepileptic drugs. Zonisamide was synthesized by the sulfonation and the successive amination of 1,2-benzisoxazole-3-acetic acid in a very poor yield. After several efforts to optimaize the compound, zonisamide was selected based on the balance of the efficacy and safety. The yield was greatly improved by the development of new synthetic routes. Zonisamide suppressed maximal electroshock seizures in mice, rats, rabbits and dogs. Its therapeutic plasma concentration range between anticonvulsant and neurotoxic effects was much wider than that of the existing antiepileptic drugs. In electroencephalographic studies on animal models of epilepsy, zonisamide, like phenytoin and carbamazepine, restricted the spread or propagation of seizures and, like sodium valproate, it suppressed the epileptogenic focus activity. Zonisamide was effective in several kindling models. In clinical studies, zonisamide exerted the efficacy against partial seizures (simple, complex, secondarily generalized seizures and some generalized seizures (tonic-clonic, tonic, atypical absence seizures) that were comparable to that of carbamazepine and sodium valproate, respectively. Zonisamide was also effective in monotherapy. The adverse effects related with zonisamide were mainly drowsiness, ataxia, loss of appetite and gastrointestinal symptoms. Serious adverse effects which may be life-threatening have not been reported.

Overview of Japanese experience-controlled and uncontrolled trials

Zonisamide is a new type of benzisoxazole derivative, first marketed in Japan in 1989. This study analyzed: (1) the drug’s efficacy by seizure and epilepsy type in a total of 1008 patients treated during the development of zonisamide in Japan; (2) the effectiveness of zonisamide for 726 newly-diagnosed patients treated with zonisamide postmarketing; and (3) 50 patients with generalized epilepsies and epileptic syndromes (idiopathic generalized epilepsies, symptomatic generalized epilepsies, Lennox-Gastaut syndrome, Doose syndrome, and West syndrome), and 19 patients with undetermined epilepsies and specific syndromes (refractory grand mat in childhood, severe myoclonic epilepsy in infancy, other undetermined epilepsy, familial. essential myoclonic epilepsy, and mitochondrial encephalomyopathy with ragged-red fibers). Analysis of study results showed that among all patients treated, zonisamide was highly effective for the treatment of idiopathic generalized epilepsy, temporal lobe epilepsy, and other partial epilepsies. The compound was also effective for other symptomatic generalized epilepsies. In 50 patients with generalized epilepsies, and 19 with undetermined epilepsies and specific syndromes, seizure frequency was reduced by >50% with monotherapy or two-drug therapy with zonisamide. Zonisamide was effective not only for partial epilepsies and generalized epilepsies but also for undetermined epilepsies and specific syndromes such as myoclonus epilepsy. (C) 2004 BEA Trading Ltd.
