A 15N NMR Study of Some Azoles

15N NMR data are reported for 42 azoles, taken mostly at a standard concentration and in a common solvent (0.5 M dimethyl sulfoxide with a 0.01 M increment of Cr(acac)3 for each nitrogen atom present).Signal assignments were assisted by comparison with 14N line widths, the use of 2J(15N1H) couplings, and shielding calculations obtained by the INDO/S-SOS approach.The generally large differences in nitrogen-shielding changes permitted rather facile shift assignments.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of Benzo[d]isothiazole, you can also check out more blogs about272-16-2

New disulfide route to 3-(1-piperazinyl)-1,2-benzisothiazole. Nucleus for atypical antipsychotic drugs

A new, one-step commercial process for the preparation of 3-(1-piperazinyl)-l,2-benzisothiazole hydrochloride, a key intermediate for the syntheses of some new, “atypical antipsychotic” drugs, was developed. Reaction of bis(2-cyanophenyl) disulfide with excess piperazine at 120-140 C for 3-24 h in the presence of small amounts of DMSO and 2-propanol formed 3-(l-piperazinyl)-l,2-benzisothiazole in 75-80% yields. The DMSO oxidized the liberated 2-mercaptobenzonitrile to regenerate bis(2-cyanophenyl) disulfide, thereby enabling the utilization of both halves of the symmetrical disulfide to generate product. The reaction mechanism for the conversion of the bis(2-cyanophenyl) disulfide to 3-amino-1,2-benzisothiazole involves the formation of ring-opened sulfenamide and benzamidine intermediates and then their subsequent ring closure to regenerate the 1,2-benzisothiazole nucleus. A safe, efficient, and robust process to prepare 3-(l-piperazinyl)-1,2-benzisothiazole under very concentrated reaction conditions was developed and successfully scaled up in the pilot plant to support the development of ziprasidone.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Lurasidone: efficacy and safety in the treatment of psychotic and mood disorders

Introduction: Lurasidone ([3aR,4S,7R,7aS]-2-[(1R,2R)-2-[4-(1,2-benzisothiazol-3-yl)piperazin-1yl-methyl] cyclohexylmethyl]-hexahydro-4,7-methano-2H-isoindole-1,3-dione hydrochloride; Latuda) is a novel benzisothiazole, second-generation antipsychotic drug developed by Dainippon Sumitomo Pharma Corporation in Japan. Similar to other atypical antipsychotics it has a distinctive pharmacodynamic profile, Areas covered: This review updates reported research findings on the efficacy, safety and tolerability of LRSD for treatment of psychotic and major affective disorders, with meta-analyses. Short-term efficacy of LRSD in schizophrenia is supported by several randomized, controlled trials with daily doses of 40?160?mg, yielding relatively modest symptomatic improvements. Lurasidone has regulatory approval for treatment of undefined duration in schizophrenia. Long-term benefits and effects in schizophrenia, and both short- and long-term use for other psychotic disorders and mania have not been tested. LRSD shows unusual efficacy in acute bipolar depression even without psychotic features. However, trials of adding LRSD to lithium or valproate for bipolar disorder have yielded inconsistent findings. Expert opinion: Available research findings indicate that LRSD is effective and well-tolerated for short-term treatment of schizophrenia, and for acute bipolar depression. It has low risk of inducing weight-gain, metabolic, or cardiac abnormalities, but its risk of akathisia may exceed that of other modern antipsychotics. Needed is adequate long-term testing in schizophrenia and bipolar disorder and testing for other indications, including against alternative treatments.

Continuation of structure?activity relationship study of novel benzamide derivatives as potential antipsychotics

A series of benzamide derivatives possessing potent dopamine D2, serotonin 5-HT1A, and 5-HT2A receptor properties were synthesized and evaluated as potential antipsychotics. Among them, 5-(4-(4-(benzo[d]isothiazol-3-yl)piperazin-1-yl)butoxy)-N-cyclopropyl-2-fluorobenzamide (4k) held the best pharmacological profile. It not only exhibited potent and balanced activities for the D2, 5-HT1A, and 5-HT2A receptors, but was also endowed with low to moderate activities for the 5-HT2C, H1, and M3 receptors, suggesting a low propensity for inducing weight gain or diabetes. In animal models, compound 4k reduced phencyclidine-induced hyperactivity with a high threshold for catalepsy or muscle relaxation induction. On the basis of its robust in vitro potency and in vivo efficacy in preclinical models of schizophrenia, 4k was selected as a candidate for further development.

Data on free and bound volatile compounds in six Ribes nigrum L. blackcurrant cultivars

The data investigated 198 volatile compounds of six currant cultivars grown in China which is analyzed by SPME?GC?MS. Volatile compounds in these currant samples were identified by two methods, comparing retention indices with reference standards and matching mass spectrum in the NST11 library. A synthetic currant matrix prepared according to the currant juice condition were extracted and analyzed using the same extraction procedure as the currant samples. The standard curve was generated for quantification of volatile compounds. For the volatiles without the available standard, the data provided consulting standards that had the same carbon atom or the similar functional structure for quantification. Further interpretation and discussion can be seen in article entitled ?Characterization of Free and Bound Volatile Compounds in Six Ribes nigrum L. Blackcurrant Cultivars? (Liu et al., 2018) [1].

A thiadiazole reduces the virulence of xanthomonas oryzae pv. Oryzae by inhibiting the histidine utilization pathway and quorum sensing

Thiazole, isothiazole, thiadiazole and their derivatives are widely thought to induce host defences against plant pathogens. In this article, we report that bismerthiazol, a thiadiazole molecule, reduces disease by inhibiting the histidine utilization (Hut) pathway and quorum sensing (QS). Bismerthiazol provides excellent control of bacterial rice leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo), but does not greatly inhibit Xoo growth in vitro. According to RNA-sequencing analysis, the transcription of the Hut pathway genes of Xoo ZJ173 was inhibited after 4.5 and 9.0 h of bismerthiazol treatment. Functional studies of hutG and hutU indicated that the Hut pathway had little effect on the growth and bismerthiazol sensitivity of Xoo in vitro, but significantly reduced the aggregation of Xoo cells. Deletion mutants of hutG or hutU were more motile, produced less biofilm and were less virulent than the wild-type, indicating that the Hut pathway is involved in QS and contributes to virulence. The overexpression of the hutG-U operons in ZJ173 reduced Xoo control by bismerthiazol. Bismerthiazol did not inhibit the transcription of Hut pathway genes, QS or virulence of the bismerthiazol-resistant strain 2-1-1. The results indicate that bismerthiazol reduces Xoo virulence by inhibiting the Hut pathway and QS.

Asymmetric synthesis of sultams and sulfonamides via diastereoselective reduction of N-sulfonylimines

The diastereoselective reduction of both cyclic and acyclic camphor sulfonylimines was investigated. With cyclic camphor sulfonylimines 1, reduction using NaBH4 in methanol afforded the corresponding camphorsultams 2 in 92-95% yield as single diastereomers with the exception of 1c where debromination occurred prior to reduction. For the large scale preparation of camphorsultam 1a and its derivatives, important chiral auxiliaries in asymmetric synthesis, reduction with NaBH4 is the reagent of choice. Reduction of acyclic camphor sulfonylimines 7 to camphorsulfonamides 8 with the bulky reducing reagent, LiAl(OBu-i)3H afforded the highest de’s (>90% de) and yields 90-95%.
