  Catechol Pyrazolinones as Trypanocidals: Fragment-Based Design, Synthesis, and Pharmacological Evaluation of Nanomolar Inhibitors of Trypanosomal Phosphodiesterase B1

  摘要：

  Trypanosomal phosphodiesterases B1 and B2 (TbrPDEB1 and TbrPDEB2) play an important role in the life cycle of Trypanosoma brucei, the causative parasite of human African trypanosomiasis (HAT), also known as African sleeping sickness. We used homology modeling and docking studies to guide fragment growing into the parasite-specific P-pocket in the enzyme binding site. The resulting catechol pyrazolinones act as potent TbrPDEB1 inhibitors with IC50 values down to 49 nM. The compounds also block parasite proliferation (e.g., VUF13525 (20b): T. brucei rhodesiense IC50 = 60 nM, T. brucei brucei IC50 = 520 nM, T. cruzi = 7.6 mu M), inducing a typical multiple nuclei and kinetoplast phenotype without being generally cytotoxic. The mode of action of 20b was investigated with recombinantly engineered trypanosomes expressing a cAMP-sensitive FRET sensor, confirming a dose-response related increase of intracellular cAMP levels in trypanosomes. Our findings further validate the TbrPDEB family as antitrypanosomal target.

  A series of fluorescent benzazepine ligands for the arginine-vasopressin V-2 receptor (AVP V2R) was synthesized using "Click" chemistry. Their in vitro pharmacological profile at AVP V2R, V1aR, V1bR, and oxytocin receptor was measured by binding assay and functional studies. Compound 9p, labeled with Lissamine Rhodamine B using novel solid-phase organic tagging (SPOrT) resin, exhibited a high affinity for V2R (4.0 nM), an excellent selectivity toward V2R and antagonist properties. By changing the nature of the dye, DY647 and Lumi4-Tb probes 44 and 47 still display a high affinity for V2R (5.6 and 5.8 nM, respectively). These antagonists constitute the first high-affinity selective nonpeptidic fluorescent ligands for V2R. They enabled the development of V2R time-resolved FRET-based assay readily amenable to high-throughput screening. Taking advantage of their selectivity, these compounds were also successfully involved in the study of V1aR-V2R dimerization on cell surface.
