Fluorophenylalkyl-substituted cyanoguanidine derivatives as bacteria-selective MATE transporter inhibitors for the treatment of antibiotic-resistant infections
A σ1 receptor pharmacophore derived from a series of N-substituted 4-azahexacyclo[5.4.1.02,6.03,10.05,9.08,11]dodecan-3-ols (AHDs)
摘要:
A library of N-substituted 4-azahexacyclo[5.4.1.0(2,6).0(3,10).0(5,9).0(8,11)]dodecan-3-ols (AHDs) was synthesized and subjected to competition binding assays at sigma(1) and sigma(2) receptors, as well as off-target screening of representative members at 44 other common central nervous system (CNS) receptors, transporters, and ion channels. Excluding 3 low affinity analogs, 31 ligands demonstrated nanomolar K-i values for either sigma receptor subtype. Several selective sigma(1) and sigma(2) ligands were discovered, with selectivities of up to 29.6 times for sigma(1) and 52.4 times for sigma(2), as well as several high affinity, subtype non-selective ligands. The diversity of structures and sigma(1) affinities of the ligands allowed the generation of a sigma(1) receptor pharmacophore that will enable the rational design of increasingly selective and potent sigma(1) ligands for probing sigma(1) receptor function.

protein-coupled receptors known as LPA1–6. A high throughput screen against LPA1 gave compound 7a as a hit. The subsequent optimization of 7a led to ONO-7300243 (17a) as a novel, potent LPA1 antagonist, which showed good efficacy in vivo. The oral dosing of 17a at 30 mg/kg led to reduced intraurethral pressure in rats. Notably, this compound was equal in potency to the α1 adrenoceptor antagonist tamsulosin
