The synthesis of 3-(dimethylamino)-2,2-dimethyl(1-15N)-2H-azirine (1*) was accomplished via reaction of 1-chloro-N,N,2-trimethyl-1-propenylamine (9) and sodium (1-15N) azide (Scheme 3).The earlier reported reactions of 1 with saccharin (10, Scheme 4), phthalimide (12, Scheme 5), and 2H-1,3-benzoxazin-2,4(3H)-dione (16, Scheme 6) were repeated with 1*, and the position of the 15N-label in the products was determined by 15N-NMR spectroscopy.Whereas the postulated reaction mechanismus for 10 and 12 were confirmed by those experiments, the mechanism for the reaction of 16 had to be revised.With respect to the position of 15N in the products 17 and 18, a new mechanism is formulated in Scheme 7.Treatment of 5,5-dimethyl-1,3-oxazolidine-2,4-dione (19) with 1* led to 3,4-dihydro-2H-imidazol-2-on 20 in which only N(3) was labelled.The mechanism of a ring expansion and transannular ring contraction as shown in Scheme 8 is in agreement with this finding.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Computed Properties of C5H7NO3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 695-53-4, in my other articles.

A topological virtual screening (tvs) test is presented, which is capable of identifying new drug leaders with anticonvulsant activity. Molecular structures of both anticonvulsant-active and non active compounds, extracted from the Merck Index database, were represented using topological indexes. By means of the application of a linear discriminant analysis to both sets of structures, a topological anticonvulsant model (tam) was obtained, which defines a connectivity function. On the basis of this model, 41 new structures with anticonvulsant activity have been identified by a topological virtual screening.

Dravet syndrome is a rare and severe encephalopathy that first presents in infancy with seizures refractory to conventional antiepileptic drugs. Forty-five percent of patients report four or more tonic?clonic seizures per month despite multidrug regimens. Fenfluramine, an amphetamine derivative, was initially developed as an appetite suppressant with a serotonergic mechanism of action. Clinical observation of a potential antiepileptic activity in a small homogeneous cohort of patients combined with a genetic workup of these patients led to the hypothesis of fenfluramine as a treatment for seizures in Dravet syndrome. This concept was successfully evaluated in a zebrafish model and led to a Phase 3 trial of fenfluramine to treat seizures in children with Dravet syndrome. Preliminary results of the trial suggest that fenfluramine may be a highly effective, well-tolerated treatment for patients with Dravet syndrome. This short review summarizes the history of use of fenfluramine from the initial clinical observations followed by preclinical studies and subsequent successful clinical trial.

The present invention is in the area of administration forms and delivery systems for drugs, vaccines and other biologically active agents. More specifically the invention is related to the preparation of suspensions of colloidal solid lipid particles (SLPs) of predominantly anisometrical shape with the lipid matrix being in a stable polymorphic modification and of suspensions of micron and submicron particles of bioactive agents (PBAs); as well as to the use of such suspensions or the lyophilizates thereof as delivery systems primarily for the parenteral administration of preferably poorly water-soluble bioactive substances, particularly drugs, and to their use in cosmetic, food and agricultural products. SLPs and PBAs are prepared by the following emulsification process: (1) A solid lipid or bioactive agent or a mixture of solid lipids or bioactive agents is melted. (2) Stabilizers are added either to the lipid or bioactive agent and to the aqueous phase or to the aqueous phase only depending on their physicochemical characteristics. (3) Drugs or other bioactive substances to be incorporated into the SLPs may be melted together with the lipids if the physicochemical characteristics of the substance permit or may be dissolved, solubilized or dispersed in the lipid melt before homogenization. (4) The aqueous phase is heated to the temperature of the melt before mixing and may contain for example stabilizers, isotonicity agents, buffering substances, cryoprotectants and/or preservatives. (5) The molten lipid compounds and the bioactive agents are emulsified in an aqueous phase preferably by high-pressure homogenization.

Background/Aims: Our study aimed to evaluate the effect of oral litholysis in patients with chronic calcific pancreatitis (CCP) unresponsive to or ineligible for extracorporeal shock wave lithotripsy (ESWL) and endoscopic therapy. Methods: Trimethadione, an antiepileptic agent, was administered orally at a dose of 0.6-0.9 g/day to 15 patients with this condition. Treatment outcome was evaluated by assessment of dissolution of the pancreatic stones on plain X-ray films and computed tomography scans of the upper abdomen. Plasma glucose, hemoglobin A1c, and body mass index (BMI) were also monitored throughout the therapy. Results: Litholysis was observed in 13 out of 15 patients (86.7%) and was definite in 10 and partial in 3. Six patients had pancreatitis attacks during the therapy; 5 of whom showed definite litholysis and had only 1 mild attack. Of the 11 patients with normal or impaired glucose tolerance at baseline, none developed diabetes mellitus and all showed litholysis. BMI significantly increased in patients whose pancreatic stones dissolved. There was no vital organ impairment by trimethadione. Conclusion: Oral litholysis using trimethadione may represent a noninvasive and effective complementary treatment in patients with CCP unresponsive to or ineligible for ESWL and endoscopic therapy.

Purpose: There is evidence that drug-induced embryonic arrhythmia initiates phenytoin (PHT) teratogenicity. The arrhythmia, which links to the potential of PHT to inhibit a specific potassium channel (Ikr), may result in episodes of embryonic ischemia and generation of reactive oxygen species (ROS) at reperfusion. This study sought to determine whether the proposed mechanism might be relevant for the teratogenic antiepileptic drug trimethadione (TMO). Methods: Effects on embryonic heart rhythm during various stages of organogenesis were examined in CD-1 mice after maternal administration (125-1,000 mg/kg) of dimethadione (DMO), the pharmacologically active metabolite of TMO. Palatal development was examined after administration of a teratogenic dose of DMO and after simultaneous treatment with DMO and a ROS-capturing agent (alpha-phenyl-N-tert-butyl-nitrone; PBN). The Ikr blocking potentials of TMO and DMO were investigated in HERG-transfected cells by using voltage patch-clamping tests. Results: DMO caused stage-specific (gestation days 9-13 only) and dose-dependent embryonic bradycardia and arrhythmia at clinically relevant maternal plasma concentrations (3-11 mM). Hemorrhage in the nasopharyngeal part of the embryonic palate (within 24 h) preceded cleft palate in fetuses at term. Simultaneous treatment with PBN significantly reduced the incidence of DMO-induced cleft palate, from 40 to 13%. Voltage patch-clamping studies showed that particularly DMO (70% inhibition), but also TMO, had Ikr blocking potential at clinically relevant concentrations. Conclusions: TMO teratogenicity, in the same way as previously shown for PHT, was associated with Ikr-mediated episodes of embryonic cardiac arrhythmia and hypoxia/ reoxygenation damage.

Sequential carbophilic addition of organolithium reagents and N-acyliminium ion cyclization of N-phenethylimides 1 affords the substituted isoquinolones 3 in high yields, with the possibility of varying the substituent at the C-1 position of the isoquinoline ring by changing the organolithium reagent. Ready access to the isoquinoline nucleus via Parham-type cyclization of imides 2 is also described. We have shown that iodinated imides 2 tolerate the metal-halogen exchange in the presence of the imide group, and the intramolecular cyclization of the so-obtained aromatic organometallic derivatives leads to the corresponding enamides 4. Both approaches have allowed the efficient preparation of various types of the isoquinoline class of alkaloids, just by changing the substitution pattern on the readily available starting imides. Thus, we have developed convenient alternative routes for the synthesis of benzo[a]quinolizidones and their 2-oxa analogs, isoindoloisoquinolones, dibenzo[a,h]quinolizidones, and thiazolo- and oxazolo[4,3-a]isoquinolones.
