Item Acyclic Cucurbit[n]uril Bearing Alkyl Sulfate Ionic Groups - Electronic Supporting Data(Beilstein Journal of Organic Chemistry, 2025-01-09) Akakpo, Christian; Zavalij, Peter Y.; Isaacs, LyleThis dataset contains the electronic data files that support the publication.Item Anthracene-Walled Acyclic CB[n] Receptors: in vitro and in vivo Binding Properties toward Drugs of Abuse(Wiley, 2022-03-03) DiMaggio, Delaney; Brockett, Adam T.; Shuster, Michael; Murkli, Steven; Zhai, Canjia; King, David; O'Dowd, Brona; Cheng, Ming; Brady, Kimberly; Briken, Volker; Roesch, Matthew R.; Isaacs, LyleWe report studies of the interaction of six acyclic CB[n]-type receptors toward a panel of drugs of abuse by a combination of isothermal titration calorimetry and 1H NMR spectroscopy. Anthracene walled acyclic CB[n] host (M3) displays highest binding affinity toward methamphetamine (Kd=15 nM) and fentanyl (Kd=4 nM). Host M3 is well tolerated by Hep G2 and HEK 293 cells up to 100 μM according to MTS metabolic and adenylate kinase release assays. An in vivo maximum tolerated dose study with Swiss Webster mice showed no adverse effects at the highest dose studied (44.7 mg kg−1). Host M3 is not mutagenic based on the Ames fluctuation test and does not inhibit the hERG ion channel. In vivo efficacy studies showed that pretreatment of mice with M3 significantly reduces the hyperlocomotion after treatment with methamphetamine, but M3 does not function similarly when administered 30 seconds after methamphetamine.Item Problem Sets for Organic Spectroscopy(2018) Isaacs, LyleThis folder contains organic structural spectroscopy problems used by Dr. Isaacs in his Chemistry 460 course at the University of Maryland. Each problem contains 1H, 13C, DEPT, COSY, HSQC, and HMBC NMR spectra that were simulated using the commercially available software from Advanced Chemistry Development. These problems can be used in two different ways: 1) the students are provided the structure and asked to assign all the resonances, and 2) the students are given the spectra and asked to deduce the structures. The answer key is password protected. Instructors can email Dr. Isaacs at LIsaacs@umd.edu to request the password.Item Book of Abstracts: 8th International Symposium on Macrocyclic and Supramolecular Chemistry(2013-07-07) Davis, Jeffery; Flood, Amar; Isaacs, LyleThis pdf file is the finalized version of the book of abstracts for the 8th International Symposium on Macrocyclic Chemistry held in Arlington, Virginia, USA from July 7-11, 2013
