A novel bifunctional chelating agent based on bis(hydroxamamide) for 99mTc labeling of polypeptides

This paper describes the synthesis and biological evaluation of a novel bifunctional chelating agent (BCA) based on bis(hydroxamamide) for 99mTc labeling of polypeptides. We successfully designed and synthesized C3(BHam)2¡¤COOH as a new BCA. C 3(BHam)2¡¤COOH formed a stable 99mTc complex and enabled us to prepare 99mTc-labeled polypeptides by using a 2,3,5,6-tetrafluorophenol (TFP) active ester of C3(BHam) 2¡¤COOH. 99mTc-C3(BHam) 2¡¤HSA prepared with C3(BHam)2¡¤TFP was stable in both murine plasma and an excess of l-cysteine without any dissociation of 99mTc from polypeptides. Furthermore, the blood clearance of 99mTc-C3(BHam)2¡¤HSA in mice was similar to that of 125I-HSA, suggesting that C 3(BHam)2¡¤COOH retained stable binding between 99mTc and the polypeptides in vivo. When 99mTc-C 3(BHam)2¡¤NGA was injected into mice, the radioactivity showed high hepatic uptake early on and a rapid clearance from the liver, indicating that C3(BHam)2¡¤COOH did not affect the pharmacokinetics of polypeptides in vivo and gave radiometabolites, which displayed a rapid elimination from the liver. Such characteristics would render C3(BHam)2¡¤COOH attractive as a new BCA for 99mTc labeling of polypeptides. Copyright

Novel benzisoxazole derivatives as potent and selective inhibitors of acetylcholinesterase

A series of N-benzylpiperidine benzisoxazoles has been developed as potent and selective inhibitors of the enzyme acetylcholinesterase (AChE). The benzisoxazole heterocycle was found to be an appropriate bioisosteric replacement for the benzoyl functionality present in the N-benzylpiperidine class of inhibitors. The title compounds were synthesized by alkylating 3- methyl-1,2-benzisoxazoles with an iodo piperidine derivative as the key step. Benzisoxazoles 1b-j,o displayed potent inhibition of AChE in vitro with IC50’s = 0.8-14 nM. Particularly interesting were N-acetyl and morpholino derivatives 1g (IC50 = 3 nM) and 1j (IC50 = 0.8 nM), respectively, which displayed outstanding selectivity for acetyl- over butyrylcholinesterase, in excess of 3 orders of magnitude. N-acetyl 1g also displayed a favorable profile in vivo. This analog showed a dose-dependent elevation of total acetylcholine in mouse forebrain after oral administration with an ED50 = 2.4 mg/kg. In addition, 1g was able to reverse amnesia in a mouse passive avoidance model at doses of 3.2 and 5.6 mg/kg with an average reversal of 89.7%. Molecular dynamics simulations were used to study the possible binding modes of N-benzylpiperidine benzisoxazoles to AChE from Torpedo californica. Key structural insights were obtained regarding the potency of this class of inhibitors. Specifically, Asp-72, Trp-84, Trp-279, Phe-288, and Phe-330 are implicated in the binding of these inhibitors. The N-benzylpiperidine benzisoxazoles may be suitable compounds for the palliative treatment of Alzheimer’s Disease.
