Mu opioid receptors (MOR-1) mediate the biological actions of clinically used opioids such as morphine, oxycodone, and fentanyl. The mu opioid receptor gene, OPRM1, undergoes extensive alternative splicing, generating multiple splice variants. One type of splice variants are truncated variants containing only six transmembrane domains (6TM) that mediate the analgesic action of novel opioid drugs such as 3′-iodobenzoylnaltrexamide (IBNtxA). Previously, we have shown that IBNtxA is a potent analgesic effective in a spectrum of pain models but lacks many side-effects associated with traditional opiates. In order to investigate the targets labeled by IBNtxA, we synthesized two arylazido analogs of IBNtxA that allow photolabeling of mouse mu opioid receptors (mMOR-1) in transfected cell lines and mMOR-1 protein complexes that may comprise the 6TM sites in mouse brain. We demonstrate that both allyl and alkyne arylazido derivatives of IBNtxA efficiently radio-photolabeled mMOR-1 in cell lines and MOR-1 protein complexes expressed either exogenously or endogenously, as well as found in mouse brain. In future, design and application of such radio-photolabeling ligands with a conjugated handle will provide useful tools for further isolating or purifying MOR-1 to investigate site specific ligand–protein contacts and its signaling complexes.

Visible light-promoted and gold-photoredox-catalyzed reactions of heteroatom (N, S, Se, O) tethered alkynes with arenediazonium salts selectively proceeded to build vicinal diaryl-substituted 2H-benzo[e][1,2]thiazine 1,1-dioxides (benzosultams), benzoselenophenes, benzothiophenes, 4H-chromen-4-ones (flavones), 3H-indoles, 1H-isochromen-1-ones (isocoumarins), and 4H-thiochromen-4-ones (thioflavones). Moreover, the utility of functionalized 3H-indoles as precursors for further elaboration has been demonstrated with the switchable and facile preparation of 1H-indoles, 2-oxindoles, and 3-oxindolines.

The addition of InBr3 to the oxidative Sonogashira cross-coupling reaction of 2-ethynylaniline with (E)-trimethyl(3,3,3-trifluoroprop-1-enyl)silane led to a dramatic increase in the reactivity to afford the corresponding 1,3-enynes bearing a trifluoromethyl group on their terminal sp2 carbon. The subsequent cyclization of these 1,3-enynes under palladium catalysis provides access to the corresponding indoles bearing a 3,3,3-trifluoroprop-1-enyl group at their 2-position.

Provided are compounds of formula (Ia) and pharmaceutically acceptable salts thereof, wherein A, B, R 1, R 2, m and n are as defined herein, which are active as inhibitors of S-Nitrosoglutathione reductase (GSNOR). These compounds prevent, inhibit, or suppress the action of GSNOR and are therefore useful in the treatment of GSNOR mediated diseases, disorders, syndromes or conditions such as, e.g., pulmonary hypertension, acute respiratory distress syndrome (ARDS), asthma, bronchospasm, cough, pneumonia, pulmonary fibrosis, interstitial lung diseases, cystic fibrosis and chronic obstructive pulmonary disease (COPD).

Synthesis and evaluation of bidentate ligands designed to interact with PDZ domains
Boucherle, Benjamin,Vogrig, Alexandre,Deokar, Hemantkumar,Bouzidi, Naoual,Ripoche, Isabelle,Thomas, Isabelle,Marin, Philippe,Ducki, Sylvie
scheme or table, p. 4346 - 4354 (2011/08/10)
We designed bidentate ligands to target PDZ domains through two binding sites: site S0, delimited by the GLGF loop, and site S1, a zone situated around loop βB/βC. A molecular docking study allowed us to design a generic S0 binder, to which was attached a variable size linker, itself linked to an amino acid aimed to interact with the S1 site of PDZ domains. A series of 15 novel bidentate ligands was prepared in 6-11 steps in good overall yield (24-43%). Some of these ligands showed an inhibitory activity against serotonin 5-HT2A receptor/PSD-95 interaction. This was assessed by pull-down assay using a synthetic decapeptide corresponding to the C-terminal residues of the receptor as a bait.

Page/Page column 140, (2010/06/17)
This invention relates to novel analogs of the DNA-alkylating agent CC-1065 and to their conjugates. Furthermore this invention concerns intermediates for the preparation of said agents and conjugates. The conjugates are designed to release their (multiple) payload after one or more activation steps and/or at a rate and time span controlled by the conjugate in order to selectively deliver and/or controllably release one or more of said DNA alkylating agents. The agents, conjugates, and intermediates can be used to treat an illness that is characterized by undesired (cell) proliferation. As an example, the agents and the conjugates of this invention may be used to treat a tumor.
