| Stage | Strategy | Outcome | |------|----------|---------| | | High‑throughput screening of a 2 M heterocyclic library on a radioligand displacement assay ([(³H)]U‑69,593). | Hit: 1‑(4‑pyridyl)piperazinyl‑phenyl‑urea scaffold (IC₅₀ ≈ 150 nM). | | Lead optimisation | Iterative SAR focused on (i) trifluoromethyl substitution on the phenyl ring to improve KOR affinity, (ii) piperazine N‑alkylation to modulate metabolic stability, (iii) urea carbonyl orientation to reduce MOR/DOR off‑target binding. | JUQ‑063: K i (KOR) = 0.28 nM; K i (MOR) > 10 µM; K i (DOR) > 10 µM; t₁/₂ (human microsomes) ≈ 45 min. | | Pharmacokinetic profiling | Rat, dog, and non‑human primate PK; CYP450 panel; P‑gp assay. | Oral F = 78 % (rat), 73 % (dog); plasma clearance moderate; <10 % CYP inhibition at 10 µM. | | Safety pharmacology | hERG patch‑clamp, Ames, in‑vitro micronucleus, off‑target receptor panel (100+). | No hERG inhibition (IC₅₀ > 30 µM); clean genotoxicity; <2 % activity at any off‑target ≤10 µM. | | Scale‑up | GMP synthesis via convergent route (four‑step, 45 % overall yield). | 10 kg batch produced for IND‑enabling studies. | JUQ-063

★★★★☆ (4/5) – Highly recommended for fans of Ayumi Kimito and mature dramatic arcs. This blog post balances technical depth with accessibility,
