DC67993	BRD1158-thioester	BRD1158-thioester is the precursor of BRD1158.
DC67992	BRD 1158	BRD1158 is a selective, fully reversible and brain-penetrant COX2 inhibitor . It has a rapid target kon and koff rates which makes it a good candidate as a PET radiotracer to monitor enzyme dynamics in vivo. The radiotracer BRD1158 is particuarly suited for imaging in tissues (such as microglia) where basal COX2 expression is very low, and has demonstrated its in vivo imaging potential in rodent models that express human COX2 (including a mouse Huntington's disease model in which COX2 expression is elevated in disease-affected brain regions).
DC67548	NOP-1A	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.
DC67547	NOP-1A Precursor	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.
DC67437	PI-2620 precursor	PI-2620 precursor is the precursor of PI2620. 18F-PI-2620 is a PET tracer with high binding affinity for aggregated tau, a key pathologic feature of Alzheimer disease (AD) and other neurodegenerative disorders.
DC60818	mono-Boc-Br MK-6240 Precursor	mono-Boc-Br MK-6240 Precursor is the precusor of MK-6240.. (18)F]-MK-6240 is a tau positron emission tomography (PET) tracer for neurofibrillary tangles (NFTs), exhibiting high specificity and selectivity for binding to NFTs .
DC67285	DOTA-Octreotide
DC67284	NOTA-NOC
DC60791	Cholestify Precursor	Precursor of Cholestify,18F-Cholestify, which binds cytochrome P450 46A1, detected cholesterol breakdown in the mammalian brain. CYP46A1 converts cholesterol to 24-hydroxycholesterol, a form easily eliminated from the brain.
DC60790	DesMEM AZD4694	DesMEM AZD4694（AZD4694 Precursor 1）is the precursor of [18F] AZD4694 for the synthesis of [18F] AZD4694, an amyloid-β imaging ligand with high affinity for amyloid-β plaques.
