Oxazolidine-2-thiones and Thiazolidine-2-thiones as Nucleophiles in Intermolecular Michael Additions

Conjugate addition of thiazolidinethiones and oxazolidinethiones to N-crotonylthiazolidinethiones and -oxazolidinethiones was observed in the presence of excess triethylamine in dichloromethane. The addition takes place by the nitrogen of the heterocycle with high diastereoselectivity. It was observed that the stereoselective addition occurs on the anti-s-cis conformation of the N-enoyl sulfur-containing heterocycle.

Design and synthesis of a folate-receptor targeted diazepine-ring-opened pyrrolobenzodiazepine prodrug conjugate

Pyrrolobenzodiazepines (PBDs) and their dimers (bis-PBDs) have emerged as some of the most potent chemotherapeutic compounds and are currently under development as novel payloads in antibody-drug conjugates (ADCs). However, when used as stand-alone therapeutics or as warheads for small molecule drug conjugates (SMDCs), dose-limiting toxicities are often observed. As an elegant solution to this inherent problem, we designed and synthesized a diazepine-ring-opened bis-PBD prodrug (pro-PBD-PBD) folate conjugate lacking the one of the two imine moieties found in the corresponding free bis-PBD. Upon entering a targeted cell, cleavage of the linker system, including the hydrolysis of an oxazolidine moiety, results in the formation of a reactive intermediate which possesses a newly formed aldehyde as well as an aromatic amine. A fast and spontaneous intramolecular ring-closing reaction subsequently takes place as the aromatic amine adds to the aldehyde with the loss of water to give the imine, and as a result, the diazepine ring, thereby delivering the bis-PBD to the targeted cell. The in vitro and in vivo activity of this conjugate has been evaluated on folate receptor positive KB cells. Sub-nanomolar activity with good specificity and high cure rates with minimal toxicity have been observed.

Oligomer Formation in Epoxy-Dicyandiamide Systems

For epoxy adhesives based on the hardener dicyandiamide (Dicy), the literature offers different reaction schemes about how epoxy resin and Dicy react. Since these propositions are inconsistent, a complete description of the network formation regarding both tautomeric structures of Dicy does not exist currently. In this study, the oligomer formation before gelation is considered for a pre-cured epoxy system EP [diglycidylether of bisphenol A (DGEBA) + Dicy, mass ratio 100: 7] by reversed-phase HPLC, mass spectrometry, and FTIR spectroscopy analysis. The results verify that DGEBA and Dicy react to 2-cyanimido oxazolidine and ammonia or to 2-imino oxazolidine and cyanamide via Gilbert’s or Zahir’s cyclization, depending on the tautomer. Both chemical pathways go on simultaneously as proven for the first time. Other reactions proposed in the literature (transformation of imino ether to urea or urethane species) are not found under the given conditions (150 degrees C, 60 min).

Probing the Reactivity of Cyclic N,O-Acetals versus Cyclic O,O-Acetals with NaBH4 and CH3MgI

An operationally straightforward, project-like laboratory experiment has been developed in which students directly compare the reactivity of two heterocycles, a cyclic O,O-acetal (standard C=0 protecting group) and a cyclic N,O-acetal (oxazolidine), toward sodium borohydride and methylmagnesium iodide. Students synthesize a substrate containing both structural features, and then experimentally establish the chemo- and regioselective ring-opening of the N,O-acetal by identifying their 2-amino-l-alkanol products through spectral analysis. This experiment demonstrates that nonaromatic N- and O-heterocycles beyond those usually encountered by students in introductory organic textbooks, such as O,O-acetals and epoxides, are also reactive to nucleophiles, and it emphasizes the great effect on chemical reactivity of a seemingly minor structural alteration: exchanging 0 for N in a heterocycle.

Metabolism of a Serotonin-4 Receptor Partial Agonist 4-{4-[4-Tetrahydrofuran-3-yloxy)-Benzo[d]Isoxazol-3-yloxymethyl]-Piperidin-1-ylmethyl}-Tetrahydropyran-4-ol (TBPT): Identification of an Unusual Pharmacologically Active Cyclized Oxazolidine Metabolite in Human

4-{4-[4-Tetrahydrofuran-3-yloxy)-benzo[d]isoxazol-3-yloxymethyl]-piperidin-1-ylmethyl}-tetrahydropyran-4-ol (PF-4995274, TBPT) is a new agent that is a partial agonist of the human serotonin-4 (5-HT4) receptor and is under investigation for neurological disorders. Metabolism of TBPT was examined in vitro in human liver microsomes and human hepatocytes. Metabolites were also identified in the plasma of healthy human subjects in a phase 1 clinical study. Human-derived metabolite profiles were compared with corresponding profiles obtained in laboratory animal species. There were two major routes of metabolism in vitro: N-dealkylation of the methyltetrahydropyran moiety (M1) and hydroxylation at the seven position of the benzisoxazole moiety (M4). These were also observed in human plasma; however, in that matrix, the major metabolite was an unusual cyclized oxazolidine entity (M2). M2 was proposed to be formed via generation of an intermediate 4. iminium ion on the piperidine ring followed by spontaneous cyclization by attack of the beta-hydroxyl substituent of the tetrahydropyran ring to form a cyclized oxazolidine product. An authentic standard of the metabolite was generated using a methylene-blue-sensitized photochemical oxidation reaction as well as microbial transformation. Further investigation of this metabolite showed that it also possessed 5-HT4 agonism activity similar to the parent. The metabolite was 150-fold more highly protein bound in human plasma than TBPT, which is consistent with its presence as a major circulating metabolite while being only a minor metabolite in in vitro systems. Overall, this illustrates the importance of understanding the complex dispositional properties of a pharmacologically active metabolite. (C) 2013 Wiley Periodicals, Inc.

A Mechanistic Paradigm for Broad-Spectrum Antivirals that Target Virus-Cell Fusion

LJ001 is a lipophilic thiazolidine derivative that inhibits the entry of numerous enveloped viruses at non-cytotoxic concentrations (IC50 <= 0.5 mu M), and was posited to exploit the physiological difference between static viral membranes and biogenic cellular membranes. We now report on the molecular mechanism that results in LJ001's specific inhibition of virus-cell fusion. The antiviral activity of LJ001 was light-dependent, required the presence of molecular oxygen, and was reversed by singlet oxygen (O-1(2)) quenchers, qualifying LJ001 as a type II photosensitizer. Unsaturated phospholipids were the main target modified by LJ001-generated O-1(2). Hydroxylated fatty acid species were detected in model and viral membranes treated with LJ001, but not its inactive molecular analog, LJ025. O-1(2)-mediated allylic hydroxylation of unsaturated phospholipids leads to a trans-isomerization of the double bond and concurrent formation of a hydroxyl group in the middle of the hydrophobic lipid bilayer. LJ001-induced O-1(2)-mediated lipid oxidation negatively impacts on the biophysical properties of viral membranes (membrane curvature and fluidity) critical for productive virus-cell membrane fusion. LJ001 did not mediate any apparent damage on biogenic cellular membranes, likely due to multiple endogenous cytoprotection mechanisms against phospholipid hydroperoxides. Based on our understanding of LJ001's mechanism of action, we designed a new class of membrane-intercalating photosensitizers to overcome LJ001's limitations for use as an in vivo antiviral agent. Structure activity relationship (SAR) studies led to a novel class of compounds (oxazolidine-2,4-dithiones) with (1) 100-fold improved in vitro potency (IC50<10 nM), (2) red-shifted absorption spectra (for better tissue penetration), (3) increased quantum yield (efficiency of O-1(2) generation), and (4) 10-100-fold improved bioavailability. Candidate compounds in our new series moderately but significantly (p <= 0.01) delayed the time to death in a murine lethal challenge model of Rift Valley Fever Virus (RVFV). The viral membrane may be a viable target for broad-spectrum antivirals that target virus-cell fusion.
