靶点 |
Ki:0.43±0.02nM (α1A-Adrenoceptor) |
|
体外研究 |
Specific [3H]L-771688 binding to cloned human α1A-Adrenoceptors is inhibited with high potency by subtype selective compounds,GG818 (Ki=0.026±0.002nM) and L-771688 (Ki=0.052±0.008nM) and subtype non-selective α1-adrenoceptor antagonists,prazosin (Ki=0.088±0.0.032nM) and terazosin (Ki=1.8±0.65nM).The relative amount of [3H]L-771688 (0.5nM) binding in various rat tissue membranes is highest in submaxillary gland (9.5 pmol/g tissue),followed by brain (5.8 pmol/g tissue),vas deferens (4.3 pmol/g tissue),kidney (3.4 pmol/g tissue),heart (1.5 pmol/g tissue),urethra (1.1 pmol/g tissue) and prostate (0.88 pmol/g tissue).In contrast,low specific [3H]L-771688 binding is observed in rat urinary bladder (0.55 pmol/g tissue),liver (0.44 pmol/g tissue),aorta (0.11 pmol/g tissue) and spleen (0.11 pmol/g tissue). |

细胞实验: |

|
[3H]L-771688 is prepared by a catalytic reduction of the precursor,L-797429,in the presence of tritium gas followed by preparative high pressure liquid chromatography.Receptor membranes are prepared for [3H]prazosin/[125I]HEAT binding assays.To measure [3H]L-771688 binding,980μL of membranes (cloning human α1A or rat tissues) are added to triplicate tubes containing 10μL of dimethyl sulfoxide (DMSO) (for total binding) or phentolamine (10μM final concentration,for nonspecific binding) or tested compounds (at the desiring final concentrations) and 10μL of [3H]L-771688 (0.3 to 0.6nM final concentration for routine studies and 10pM to 5nM for saturation assays).[3H]L-771688 is diluted in DMSO/methanol/water (1:1:2) from stock solution to minimize its loss to the wall of test tubes.The binding reaction is conducted at 25℃ for 1h or various time intervals in the association rate studies. |
