  • Dendrimer-Functionalized Hybrid Materials Based on Silica As Novel Carriers of Bioactive Acids
    molecules Article Dendrimer-Functionalized Hybrid Materials Based on Silica as Novel Carriers of Bioactive Acids Mateusz Pawlaczyk * and Grzegorz Schroeder Faculty of Chemistry, Adam Mickiewicz University in Pozna´n,Uniwersytetu Pozna´nskiego 8, 61-614 Pozna´n, Poland; [email protected] * Correspondence: [email protected]; Tel.: +48-61-829-17-97 Received: 9 May 2020; Accepted: 3 June 2020; Published: 8 June 2020 Abstract: One of the major goals in the materials science is the design and development of non-toxic, versatile, and efficient drug delivery systems. The study reported in this paper concerns the syntheses of poly(amidoamine) (PAMAM) dendrimers with tris(2-aminoethyl)amine as an amine core and different terminal amines, and their attachment to silica matrix. The obtained ethylenediamine (EDA), triethylenetetramine (TETA), tris(2-aminoethyl)amine (TREN) and 4,7,10-trioxa-1,13-tridecanediamine (TRI-OXA) dendrimers were introduced to the support surface via an epoxy linker, leading to a loading 1 efficiency in the range of 0.054–0.113 mmol g− , determined using elemental and thermogravimetric analyses. The materials exhibited high adsorption capacities towards the chosen model drugs: folic, salicylic and nicotinic acid. The investigated adsorption processes were found to follow the Freundlich isotherm model, with indication of the drugs’ structure influence on the binding efficiency. Drug-loaded hybrid materials were also described for in vitro drug release in three pH-different paraphysiological media. The highest percentage release was obtained in the tests performed at pH 2.0, ranging between 35.42 and 99.83%. Satisfactory results and the versatility of PAMAM dendrimers may lead to the application of such materials not only as drug carriers dedicated to a wide range of pharmaceutics, but also as analytical tools for pre-concentration and/or the determination of biocompound contamination in samples.

  • Tetraethylenepentamine Cas N°: 112-57-2
    OECD SIDS TETRAETHYLENEPENTAMINE FOREWORD INTRODUCTION TETRAETHYLENEPENTAMINE CAS N°: 112-57-2 UNEP PUBLICATIONS 1 OECD SIDS TETRAETHYLENEPENTAMINE SIDS Initial Assessment Report For 13th SIAM (Bern, Switzerland November 6-9, 2001) Chemical Name: Tetraethylenepentamine CAS No.: 112-57-2 Sponsor Country: USA SIDS Contact: Oscar Hernandez United States Environmental Protection Agency (7403M) ICC Building, room 6220A 1200 Pennsylvania Avenue, NW Washington, DC 20460 History: Tetraethylenepentamine was volunteered for the U.S. HPV program and subsequently the ICCA program by the Ethyleneamines Product Stewardship Discussion Group in the U.S. Use of data from the analog triethylenetetramine is proposed to reduce testing needs. The panel/consortia (Dow, UCC and Azko-Nobel) searched company files and publicly available databases to obtain data on TEPA. The “Environmental Risk Assessment of Complexing Agents” submitted by Germany was also included in this evaluation. Testing: No testing (x) Testing ( ) Comments: Deadline for Circulation: September 14, 2001 Date of Circulation: 2 UNEP Publications OECD SIDS TETRAETHYLENEPENTAMINE SIDS INITIAL ASSESSMENT PROFILE CAS No. 112-57-2 Chemical Name 3,6,9-triazaundecamethylenediamine; tetraethylenepentamine (TEPA) Structural Formula NH2CH2CH2NHCH2CH2NHCH2CH2NHCH2CH2NH2 RECOMMENDATIONS The chemical is currently of low priority for further work. SUMMARY CONCLUSIONS OF THE SIAR Use of Analog TETA to suppleme nt TEPA data Tetraethylenepentamine (TEPA) is similar toxicologically to triethylenetetramine (TETA) based on its structure and chelation properties. Therefore, data obtained using TETA have been used to address the endpoints for reproductive and developmental toxicity. Human Health Tetraethylenepentamine (TEPA) has a low acute toxicity when administered orally to rats (LD50 = 3250 mg/kg). In an acute inhalation toxicity study with saturated vapor and whole body exposure, the LC50 was calculated to be >9.9 ppm (highest dose tested).
