The Precursor of NOP-1A.  (11)C-NOP-1A is a useful radioligand for quantifying NOP receptors in the monkey brain, and its radiation dose is similar to that of other (11)C-labeled ligands for neuroreceptors.

NOP-1A standard. 11C-NOP-1A is a new radioligand for thenociceptin/orphanin FQ peptide (NOP) receptor, with high affinity (Ki, 0.15 nM) and appropriate lipophilicity (measured logD, 3.4) for PET brain imaging. 11C-NOP-1A is the the first successful radioligand to image NOP receptors in rat and monkey brain. 11C-NOP-1A is a selective antagonist at the NOP receptor and has high affinity and appropriate lipophilicity for blood–brain barrier permeability. 11C-NOP-1A imaging in rhesus monkeys showed high brain uptake and a large receptor-specific signal and could be quantified with the gold standard method of compartmental modeling. In humans 1C-NOP-1A reliably quantified NOP receptors in human brain both in large brain regions and at a voxelwise level using parametric imaging. The radiation absorbed dose in humans was similar to that observed with other 11C-labeled ligands and would allow multiple scans of a single subject. Thus, 11C-NOP-1A is a promising radioligand for reliably quantifying NOP receptors in human brain.

ZSH-2208 is a synthetic analog of all-trans retinoic acid (ATRA) designed to overcome resistance and improve differentiation therapy in acute promyelocytic leukemia (APL) and other malignancies. In published studies, ZSH-2208 has shown superior anti-proliferative and pro-differentiation activity compared to ATRA in ATRA-resistant APL cell lines such as NB4-R2. For example, ZSH-2208 induced significant G1 phase arrest and granulocytic differentiation in NB4-R2 cells at concentrations around 1–10 µM, whereas ATRA was largely ineffective at equivalent doses. In mouse xenograft models, ZSH-2208 treatment led to marked tumor growth inhibition without the rapid metabolic degradation seen with ATRA. These data suggest that ZSH-2208 is a promising candidate for treating retinoic acid-resistant leukemias and potentially other cancers sensitive to retinoid signaling.
