Effects on suicidal risk: Comparison of clozapine to other newer medicines indicated to treat schizophrenia or bipolar disorder was written by Forte, Alberto;Pompili, Maurizio;Imbastaro, Benedetta;De Luca, Gabriele Pasquale;Mastrangelo, Martina;Montalbani, Benedetta;Baldessarini, Ross J.. And the article was included in Journal of Psychopharmacology (London, United Kingdom) in 2021.Reference of 146939-27-7 This article mentions the following:
Background:: Clozapine is the only treatment with regulatory-recognition of lowering suicidal risk, at least in schizophrenia patients. It remains uncertain whether such effects extend to other drugs for psychosis. Methods:: We searched for reports on rates of suicidal behavior during treatment with clozapine and other modern drugs for psychosis (aripiprazole, olanzapine, risperidone, quetiapine, and ziprasidone) vs. comparison or control treatments and analyzed the contrasts by random-effect meta-anal. to obtain pooled odds ratios (ORs) with 95% confidence intervals (CIs). Results:: We identified 35 paired comparisons of modern drugs for psychosis vs. comparison or control treatments in 18 reports. There was moderate overall superiority of all agents tested over alternatives (OR = 0.522, p = 0.004). With clozapine, this effect was large (OR = 0.229, p < 0.0001) and consistent (7/7 trials), but significant antisuicidal effects were not found with other drugs for psychosis in 28 other trials (OR = 0.941, p = 0.497). Apparent efficacy of specific agents ranked: risperidone ≥ olanzapine ≥ aripiprazole ≥ ziprasidone ≥ mixed drugs for psychosis ≥ quetiapine, but none of these differences was significant. Conclusions:: An ability of clozapine to reduce risk of suicides and attempts in schizophrenia patients appears to be a unique effect not shared with other modern medicines indicated for schizophrenia or bipolar disorder. In the experiment, the researchers used many compounds, for example, 5-(2-(4-(Benzo[d]isothiazol-3-yl)piperazin-1-yl)ethyl)-6-chloroindolin-2-one (cas: 146939-27-7Reference of 146939-27-7).
5-(2-(4-(Benzo[d]isothiazol-3-yl)piperazin-1-yl)ethyl)-6-chloroindolin-2-one (cas: 146939-27-7) belongs to isothiazole derivatives. The chemistry of isothiazoles is being intensively developed, which is evidenced by the wide range of selective transformations involving the isothiazole heterocycle and the high biological activity of its derivatives that can be used as effective new drugs and plant protection chemicals. The isothiazoles can be oxidized to the corresponding sulfoxides on treatment with peracids.Reference of 146939-27-7
