radioiodinated benzoimidazopyridine (BIP) derivatives with an alkylaminogroup as tau imaging probes. In vitro selectivity to tau aggregates and in vivo pharmacokinetics of BIP derivatives varied markedly, being strongly dependent on the alkylaminogroup. In in vitro autoradiography with AD brain sections, the BIP derivative with a dimethylamino group (BIP-NMe2) showed the highest selectivity to tau aggregates

Bleomycin is considered to exert its antitumor activity via DNA cleavage mediated by activated oxygen generated from the iron complex in its chelator moiety. Spin-offs from this moiety, HPH-1Trt and HPH-2Trt, with anti-cancer activities were recently synthesized. In this paper, we developed inhibitors of nicotinamideadeninedinucleotide-dependent deacetylase isoform 2 of Sirtuin protein (SIRT2), based
