Juq-139

A panel of 12 cancer cell lines (including MDA‑MB‑231, HCT‑116, A549, PC‑3) and a non‑transformed line (MCF‑10A) were cultured in RPMI‑1640 + 10 % FBS. Cells were seeded at 5 × 10³ cells well⁻¹ in 96‑well plates, treated with serial dilutions of JUQ‑139 (0.1 nM–10 µM) for 72 h, and viability assessed using the CellTiter‑Glo luminescent assay.

| Symptom | Likely Cause | Fix | |---------|--------------|-----| | No Wi‑Fi connection | Incorrect SSID/password or 2.4 GHz vs 5 GHz mismatch | Re‑run the mobile app’s “Wi‑Fi Setup” and ensure you select the correct band. | | Sensors report “NaN” | Loose I²C connection or missing pull‑up resistors | Power down, reseat the sensor module, verify soldered pins. | | Device reboot loops | Firmware corruption or insufficient power | Perform a hard reset (hold reset button 10 s), then re‑flash firmware via USB. | | OTA update fails | Network firewall blocks TLS 1.3 | Open outbound port 443 or use a wired Ethernet connection. | | High power draw | Peripheral module drawing > 200 mA | Move power‑intensive sensors to an external supply and use a logic‑level MOSFET switch. |

A convergent synthetic plan was employed (Scheme 1). The benzothiazole fragment (A) was prepared via a Hantzsch condensation, while the pyrazolo[1,5‑a]pyridine fragment (B) was constructed through a cyclocondensation of 2‑aminopyrazine with an appropriate β‑ketoester. The two fragments were linked via a sulfonyl chloride coupling step. Full experimental details are provided in the Supporting Information (SI).

JUQ-139 is an investigational small-molecule compound (experimental designation) reported in preclinical literature and patent filings as a targeted anticancer agent with activity against receptor tyrosine kinases and related signaling pathways. It has been described primarily in medicinal chemistry and oncology-discovery contexts; public information is limited and mostly from patents, conference abstracts, and early-stage preclinical reports.

Characterization of JUQ‑139

JUQ‑139 is a newly designed heterocyclic small‑molecule that combines a 1,3‑benzothiazole core with a fused pyrazolo[1,5‑a]pyridine moiety, functionalized with a sulfonamide‑linked aryl‑alkyl side chain. The compound was conceived through a structure‑based drug‑design (SBDD) campaign targeting the ATP‑binding pocket of the oncogenic kinase PI3K‑α (phosphoinositide 3‑kinase alpha). Here we report a convergent synthetic route to JUJ‑139, its physicochemical profiling, in‑vitro kinase inhibition, cytotoxicity against a panel of cancer cell lines, and preliminary in‑vivo efficacy in a xenograft mouse model. JUQ‑139 exhibits sub‑nanomolar affinity for PI3K‑α (K_i = 0.42 nM), selective inhibition over the PI3K‑β/δ/γ isoforms (>500‑fold), and potent antiproliferative activity (IC₅₀ = 12–38 nM) in triple‑negative breast cancer (TNBC) and KRAS‑mutant colorectal cancer (CRC) cell lines. Oral administration (30 mg kg⁻¹ q.d.) in athymic nude mice bearing MDA‑MB‑231 xenografts produced a 78 % tumor growth inhibition (TGI) with no observable toxicity. These data position JUQ‑139 as a promising lead for further preclinical development toward targeted cancer therapy.
