The efficient ruthenium-catalyzed meta-selective CAr-H nitration of azole ring substituted arenes has been developed. In this work, Ru3(CO)12 was used as the catalyst, AgNO2 as the nitro source, HPcy3+·BF4- as the ligand, pivalic acid as the additive, and DCE as the solvent, and a wide spectrum of arenes bearing thiazole, pyrazolyl or removable oxazoline directing groups were tolerated in this meta-selective CAr-H nitration, affording the nitrated products in moderate to good yields. Moreover, this study reveals a gentler and environmentally friendly way to access meta-nitration arenes compared to the traditional process.

Allosteric modulators have attracted significant interest as an alternate strategy to modulate CB1 receptor signaling for therapeutic benefits that may avoid the adverse effects associated with orthosteric ligands. Here we extended our previous structure-activity relationship studies on the diarylurea-based CB1 negative allosteric modulators (NAMs) by introducing five-membered heterocycles to replace the 5-pyrrolidinylpyridinyl group in PSNCBAM-1 (1), one of the first generation CB1 allosteric modulators. Many of these compounds had comparable potency to 1 in blocking the CB1 agonist CP55,940 stimulated calcium mobilization and [35S]GTP-γ-S binding. Similar to 1, most compounds showed positive cooperativity by increasing [3H]CP55,940 binding, consistent with the positive allosteric modulator (PAM)-antagonist mechanism. Interestingly, these compounds exhibited differences in ability to increase specific binding of [3H]CP55,940 and decrease binding of the antagonist [3H]SR141716. In saturation binding studies, only increases in [3H]CP55,940 Bmax, but not Kd, were observed, suggesting that these compounds stabilize low affinity receptors into a high affinity state. Among the series, the 2-pyrrolyl analogue (13) exhibited greater potency than 1 in the [35S]GTP-γ-S binding assay and significantly enhanced the maximum binding level in the [3H]CP5,5940 binding assay, indicating greater CB1 receptor affinity and/or cooperativity.
