Dược Lực Học :
Altropane is a molecular-imaging agent that specifically binds to the dopamine transporter (DAT) protein found on the surface of dopamine-producing neurons, making it visible during SPECT imaging. Since most forms of Parkinsonian Syndromes result in a decreased number of dopamine-producing cells, it would be expected that these patients also have fewer DATs than do patients without PS. Thus, it is believed that altropane used in conjunction with SPECT imaging could be a useful test to distinguish Parkinsonian Syndrome tremors from non-Parkinsonian tremor: non-Parkinsonian patients would have more altropane-binding visible in the SPECT image, while Parkinsonian patients would have less.
Cơ Chế Tác Dụng :
Boston Life Sciences (BLS) is developing Altropane as a potential radio-imaging agent to be used with single photon emission tomography (SPECT), for the early diagnosis of Parkinson's disease (PD) and attention deficit hyperactivity disorder (ADHD).
Positron emission tomography (PET) cameras are expensive and scarce, and the tests are non-reimbursable. A less costly and more available test such as a single photon emission computed tomography (SPECT) may be helpful in the diagnosis of early or atypical Parkinson's disease (PD) if its sensitivity is comparable to a PET scan. Altropane is an iodinated form of the N-allyl analog of WIN 35,428 which acts as a dopamine transport inhibitor. When radiolabeled with the gamma emitting isotope [123I], altropane serves as a SPECT ligand with high affinity and selectivity for the dopamine transporter. It is a good marker for dopamine neurons and is useful in detecting PD.
Chỉ Định :
Investigated for use/treatment in attention deficit/hyperactivity disorder (ADHD), parkinson's disease, and pediatric indications.
