846589-98-8 Usage
Description
Different sources of media describe the Description of 846589-98-8 differently. You can refer to the following data:
1. In June 2012, the US FDA approved lorcaserin for chronic weight management
in adult patients who are characterized as overweight or obese and
have at least one comorbid, weight-related condition.
Lorcaserin (also known as APD356) is the first 5-HT2C agonist
approved for chronic weight management since the withdrawal of the
5-HT2C agonist fenfluramine in 1997 due to rare cases of cardiac valvulopathy. The serotonin receptor 5-HT2C is found primarily in the hypothalamus
and regulates appetite and feeding behavior. Safety issues with
fenfluramine were associated with poor selectivity for 5-HT2C versus
5HT2A and 5HT2B. Ring constraint afforded by the benzazepine in
lorcaserin improved selectivity for 5HT2C by over 2 log units.
2. Lorcaserin (hydrochloride) (CRM) (Item No. 19247) is a certified reference material categorized as an anorectic. It also decreases oxycodone intake and has positive effects on self-administration and relapse vulnerability in the rat. Lorcaserin is regulated as a Schedule IV compound in the United States. This product is intended for research and forensic applications.
Originator
Pharmaceuticals (United States)
Uses
Lorcaserin hydrochloride, a novel antiobesity drug, is a selective serotonin 5-HT2C receptor agonist, approved by FDA in 2012.
Definition
ChEBI: A hydrochloride obtained by reaction of lorcaserin with one equivalent of hydrochloric acid. Used as an anti-obesity drug.
Brand name
Belviq
Side effects
Lorcaserin hydrochloride (Belviq) is a serotonin 2C receptor agonist that causes weight loss by causing appetite suppression.It appears to have fewer adverse effects than orlistat,although long-term safety data are limited. The recommended dosage is 10mg twice daily. Lorcaserin should be discontinued if patients do not lose 5% of their body weight in 12 weeks. The efficacy of lorcaserin appears similar to that of orlistat (mean difference in weight loss between active and placebo-treated groups approximately 3-4 kg).Common side effects include nausea, headache,dizziness, nasopharyngitis, and fatigue. Lorcaserin may increasethe risk of symptomatic hypoglycemia in patients with type 2 diabetes on oral agents, necessitating a reduction in the dose of diabetes medications. Lorcaserin should not be used in individuals with creatinine clearance <30 mL/minute. It is contraindicated during pregnancy. In addition, lorcaserin should not be used with other serotonergic drugs (e.g., selective serotonin reuptake inhibitors,selective serotonin-norepinephrine reuptake inhibitors, bupropion[Wellbutrin], tricyclic antidepressants,and monamine oxidase inhibitors)because of the theoretical potential for serotonin syndrome.https://www.accessdata.fda.govhttps://medlineplus.gov
Check Digit Verification of cas no
The CAS Registry Mumber 846589-98-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,6,5,8 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 846589-98:
(8*8)+(7*4)+(6*6)+(5*5)+(4*8)+(3*9)+(2*9)+(1*8)=238
238 % 10 = 8
So 846589-98-8 is a valid CAS Registry Number.

Paragraph 0049; 0084; 0089, (2020/05/14)
A lorcaserin hydrochloride mini-pill is provided. The mini-pill comprises a blank pill core, a medicine loading layer, a slow-release layer and a quick-release layer in order from inside to outside. The medicine loading layer comprises lorcaserin hydrochloride, lactose monohydrate, highly substituted hydroxypropylcellulose and talcum powder. The slow-release layer comprises ethyl cellulose, highly substituted hydroxypropylcellulose, talcum powder and triethyl citrate. The quick-release layer comprises lorcaserin hydrochloride, lactose monohydrate, highly substituted hydroxypropylcellulose and talcum powder. The mass ratio of the sum of the weight of the blank pill core and the weight of the medicine loading layer to the mass of the slow-release layer is 1:(0.25-0.35). The mini-pill comprises the slow-release layer and the quick-release layer, and therefore a medicine can rapidly work and functions of the medicine in a body are prolonged. A preparing method of the lorcaserin hydrochloride mini-pill and a preparation of the lorcaserin hydrochloride mini-pill are also provided.

Paragraph 1182-1186; 1189-1192; 1197, (2019/05/30)
The present invention relates to methods for weight management that utilize modified-release dosage forms comprising (R)-8-chloro-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine salts and crystalline forms thereof. The present invention further relates to (R)-8-chloro-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine salts, crystalline forms thereof and modified-release dosage forms comprising them.
Light-Enabled Enantiodivergence: Stereospecific Reduction of Activated Alkenes Using a Single Organocatalyst Enantiomer
Hostmann, Theresa,Molloy, John J.,Bussmann, Kathrin,Gilmour, Ryan
, p. 10164 - 10168 (2019/12/24)
Light-enabled enantiodivergence is demonstrated in which the alkene substrate configuration is manipulated (E → Z) prior to organocatalytic reduction with a chiral thiourea and Hantzsch ester. This allows stereodivergent reduction to be regulated at the substrate level with high fidelity and mitigates the need for a second, enantiomeric catalyst (up to 93:07 and 95:5 er). The synthetic utility of this strategy has been demonstrated in the synthesis of the weight-loss drug (R)-Lorcaserin (Belviq) and a potent AMPA modulator.
