Organocatalytic Asymmetric N-Sulfonyl Amide C-N Bond Activation to Access Axially Chiral Biaryl Amino Acids
ARTICLE https://doi.org/10.1038/s41467-020-14799-8 OPEN Organocatalytic asymmetric N-sulfonyl amide C-N bond activation to access axially chiral biaryl amino acids Guanjie Wang1, Qianqian Shi2, Wanyao Hu1, Tao Chen1, Yingying Guo1, Zhouli Hu1, Minghua Gong1, ✉ ✉ ✉ Jingcheng Guo1, Donghui Wei 2 , Zhenqian Fu 1,3 & Wei Huang1,3 1234567890():,; Amides are among the most fundamental functional groups and essential structural units, widely used in chemistry, biochemistry and material science. Amide synthesis and trans- formations is a topic of continuous interest in organic chemistry. However, direct catalytic asymmetric activation of amide C-N bonds still remains a long-standing challenge due to high stability of amide linkages. Herein, we describe an organocatalytic asymmetric amide C-N bonds cleavage of N-sulfonyl biaryl lactams under mild conditions, developing a general and practical method for atroposelective construction of axially chiral biaryl amino acids. A structurally diverse set of axially chiral biaryl amino acids are obtained in high yields with excellent enantioselectivities. Moreover, a variety of axially chiral unsymmetrical biaryl organocatalysts are efficiently constructed from the resulting axially chiral biaryl amino acids by our present strategy, and show competitive outcomes in asymmetric reactions. 1 Key Laboratory of Flexible Electronics & Institute of Advanced Materials, Jiangsu National Synergetic Innovation Center for Advanced Materials, Nanjing Tech University, 30 South Puzhu Road, Nanjing 211816, China. 2 College -

Drugs to Avoid in Patients with Dementia
Detail-Document #240510 -This Detail-Document accompanies the related article published in- PHARMACIST’S LETTER / PRESCRIBER’S LETTER May 2008 ~ Volume 24 ~ Number 240510 Drugs To Avoid in Patients with Dementia Elderly people with dementia often tolerate drugs less favorably than healthy older adults. Reasons include increased sensitivity to certain side effects, difficulty with adhering to drug regimens, and decreased ability to recognize and report adverse events. Elderly adults with dementia are also more prone than healthy older persons to develop drug-induced cognitive impairment.1 Medications with strong anticholinergic (AC) side effects, such as sedating antihistamines, are well- known for causing acute cognitive impairment in people with dementia.1-3 Anticholinergic-like effects, such as urinary retention and dry mouth, have also been identified in drugs not typically associated with major AC side effects (e.g., narcotics, benzodiazepines).3 These drugs are also important causes of acute confusional states. Factors that may determine whether a patient will develop cognitive impairment when exposed to ACs include: 1) total AC load (determined by number of AC drugs and dose of agents utilized), 2) baseline cognitive function, and 3) individual patient pharmacodynamic and pharmacokinetic features (e.g., renal/hepatic function).1 Evidence suggests that impairment of cholinergic transmission plays a key role in the development of Alzheimer’s dementia. Thus, the development of the cholinesterase inhibitors (CIs). When used appropriately, the CIs (donepezil [Aricept], rivastigmine [Exelon], and galantamine [Razadyne, Reminyl in Canada]) may slow the decline of cognitive and functional impairment in people with dementia. In order to achieve maximum therapeutic effect, they ideally should not be used in combination with ACs, agents known to have an opposing mechanism of action.1,2 Roe et al studied AC use in 836 elderly patients.1 Use of ACs was found to be greater in patients with probable dementia than healthy older adults (33% vs. -
Hydroxydopamine Lesions of the Nucleus Accumbens and the Mglur2/3 Agonist LY379268

Nevertheless, the identification of a mechanism underlying the reinforcing properties of inhalants has been hampered by the lack of a clearly identifiable neural substrate upon which these chemicals act. One ingredient that is common to many abused inhalants is toluene, an organic solvent that is self-administered by nonhuman primates and rodents. Most drugs of abuse have been found to elicit forward locomotion in rats, an effect owing to the activation of mesoaccumbal dopamine (DA) pathways. Thus, the present study was undertaken using two different approaches to determine whether toluene-induced locomotor hyperactivity is also ultimately dependent upon DA neurotransmission in the mesolimbic nucleus accumbens (NAC). Here we report on the effects of 6-hydroxydopamine (6-OHDA) lesions of the NAC or pretreatment with the metabotropic mGlu2/3 receptor agonist LY379268 on toluene-induced locomotor activity. Both procedures, which are known to alter neurotransmission within the NAC, significantly attenuated toluene’s locomotor stimulatory effects. These results provide strong support for a central mechanism of action of inhalants, which in the past has been more typically attributed to general nonspecific mechanisms throughout the brain. -

Recently, Olney and coworkers have demonstrated severe widespread apoptotic degeneration throughout the rapidly developing brain of the 7-day-old rat after ketamine administration. Recent research at FDA has confirmed and extended Olney’s observations. These findings are cause for concern with respect to ketamine use in children. The issue of whether the neurotoxicity found in this animal model (rat) has scientific and regulatory relevance for the pediatric use of ketamine relies heavily upon confirmation of these findings that may be obtained from the conduct of an appropriate study in non-human primates. 2.0 BACKGROUND INFORMATION The issue of potential ketamine neurotoxicity in children surfaced as a result of FDA’s reluctance to approve an NIH pediatric clinical trial using this compound because of its documented neurotoxic effects in young rats (published in several papers over the last ten years by Olney and co-workers). -
The Anticholinergic Toxidrome
Poison HOTLINE Partnership between Iowa Health System and University of Iowa Hospitals and Clinics July 2011 The Anticholinergic Toxidrome A toxidrome is a group of symptoms associated with poisoning by a particular class of agents. One example is the opiate toxidrome, the triad of CNS depression, respiratory depression, and pinpoint pupils, and which usually responds to naloxone. The anticholinergic toxidrome is most frequently associated with overdoses of diphenhydramine, a very common OTC medication. However, many drugs and plants can produce the anticholinergic toxidrome. A partial list includes: tricyclic antidepressants (amitriptyline), older antihistamines (chlorpheniramine), Did you know …… phenothiazines (promethazine) and plants containing the anticholinergic alkaloids atropine, hyoscyamine and scopolamine (Jimson Weed). Each summer, the ISPCC receives approximately 10-20 The mnemonic used to help remember the symptoms and signs of this snake bite calls, some being toxidrome are derived from the Alice in Wonderland story: from poisonous snakes (both Blind as a Bat (mydriasis and inability to focus on near objects) local and exotic).
