Juq-494 May 2026

| Topic | Guidance | |-------|----------| | Obtaining the compound | Commercial vendors occasionally list “JUQ‑494” under a catalog number (e.g., “JQ‑494, 5 mg, > 98 % purity”). Verify the supplier’s certificate of analysis (CoA) and request an analytical report (LC‑MS, NMR). | | Solubility | Reported solubility: ~ 2 mg mL⁻¹ in DMSO; ~ 10 µM in aqueous buffers with ≤ 5 % DMSO. For cell‑based assays, a 10 mM DMSO stock is typical; dilute to ≤ 0.1 % DMSO final concentration. | | Assay formats | • Enzyme‑based kinase assays: Use ATP concentrations near Km (≈ 10 µM) to accurately capture potency.
• Cellular phosphorylation read‑outs: Phospho‑AKT (Ser473) in B‑cell lines is a robust surrogate. | | Stability | Stable at –20 °C for ≥ 12 months in DMSO; avoid repeated freeze‑thaw cycles. | | Safety handling | Treat as a typical small‑molecule research chemical: wear gloves, goggles, and a lab coat. Dispose of waste according to institutional hazardous‑chemical protocols. |

Without specific information on JUQ-494, any analysis remains speculative. The designation could refer to anything from a cutting-edge scientific study to a product code in a niche industry. A detailed investigation would require more context or direct access to databases and information systems that might hold records of JUQ-494.

| Aspect | Summary | |--------|---------| | Kinase inhibition | JUQ‑494 shows nanomolar potency (IC₅₀ ≈ 10–30 nM) against PI3Kδ (p110δ) and CK1ε. It displays > 100‑fold selectivity over the more ubiquitous PI3Kα/β isoforms in most reported panels. | | Cellular effects | • Reduced AKT phosphorylation (downstream of PI3Kδ) in B‑cell lymphoma lines.
• Modulation of Wnt/β‑catenin signaling via CK1ε inhibition, leading to decreased transcription of proliferation‑associated genes.
• Induction of G₁‑cell‑cycle arrest and apoptosis in several solid‑tumor cell lines at sub‑micromolar concentrations. | | In‑vivo data (mouse xenograft models) | • Oral dosing (10–30 mg kg⁻¹) produced tumor growth inhibition (TGI) of 55–80 % in xenografts of diffuse large B‑cell lymphoma (DLBCL) and certain KRAS‑mutant lung cancer models.
• Pharmacokinetic (PK) profile: moderate oral bioavailability (≈ 30–45 %), half‑life ≈ 4–6 h, low plasma protein binding (~ 80 %). | | Selectivity | Broad kinase panels (e.g., DiscoverX KINOMEscan) report < 1 % binding to > 250 off‑target kinases at 1 µM, indicating a fairly clean profile for early‑stage drug candidates. |

| Area | Rationale | |------|-----------| | B‑cell malignancies | PI3Kδ is a validated target (e.g., idelalisib, duvelisib). JUQ‑494’s dual inhibition may overcome resistance mechanisms tied to compensatory CK1ε signaling. | | Solid tumors with KRAS/PI3K pathway activation | Simultaneous blockade of PI3Kδ and CK1ε can blunt both canonical PI3K/AKT signaling and the Wnt/β‑catenin axis that often sustains KRAS‑driven growth. | | Immunomodulation | PI3Kδ inhibition modulates T‑cell and regulatory B‑cell function; early data suggest that JUQ‑494 may favor a “hot” tumor microenvironment, improving checkpoint‑inhibitor efficacy. | | Combination therapy | Pre‑clinical synergy with BTK, BCL‑2, or MEK inhibitors points to a flexible partner‑selection strategy for future clinical trials. |
