series of tetrahydroisoquinoline-based benzodiazepine dimers were synthesized and tested for in vitro cytotoxicity against a panel of cancer cell lines. Structure–activityrelationship investigation of various spacers guided by molecular modeling studies helped to identify compounds with picomolar activity. Payload 17 was conjugated to anti-mesothelin and anti-fucosylated monosialotetrahexosylganglioside

The effect of modifying the pyridyl para position of lutidine-linked bis(N-heterocyclic carbene) Pd pincer complexes is studied both experimentally (R = OMe, H, Br, and COOR) and computationally, showing a strong effect on the firstreduction potential of the complex and allowing the reduction potential to be tuned over a wide range in relation to the Hammett σp constant of the para substituent. The
A set of 27- to 39-membered pyridine macrocycles 2 and 3 has been synthesized by Williamson ethersynthesis or ring-closingmetathesis. The pyridines are 2,6-disubstituted to allow endo interactions. In addition to the length, also the nature of the aliphatic chain was varied: saturated (2) and unsaturated (3).

recognize mixed DNA sequences and for progress in targeting specific genes, it is essential to have additional classes of compounds. Compounds that can be rationallydesigned from established modules and which can bind strongly to mixed base pair DNA sequences are especially attractive. Based on extensive experience in design of minor-groove agents for AT recognition, a small library of compounds with
Macropolycycliccagecompounds were synthesized by a direct reaction between diamines and bis(bromomethyl) compounds. The procedure for constructing the polycyclic cage structure is simple and straightforward. The macropolycycliccompounds obtainable from this cyclization procedure are three-dimensional cagecompounds, and any other isomers were not obtained except for two examples. Benzene, pyridine
