Designing Active Template Molecules by Combining Computational De Novo Design and Human Chemist's Expertise
摘要:
We used a new software tool for de novo design, the "Molecule Evoluator", to generate a number of small molecules. Explicit constraints were a relatively low molecular weight and otherwise limited functionality, for example, low numbers of hydrogen bond donors and acceptors, one or two aromatic rings, and a small number of rotatable bonds. In this way, we obtained a collection of scaffold- or templatelike molecules rather than fully "decorated" ones. We asked medicinal chemists to evaluate the suggested molecules for ease of synthesis and overall appeal, allowing them to make structural changes to the molecules for these reasons. On the basis of their recommendations, we synthesized eight molecules with an unprecedented (not patented) yet simple structure, which were subsequently tested in a screen of 83 drug targets, mostly G protein-coupled receptors. Four compounds showed affinity for biogenic amine targets (receptor, ion channel, and transport protein), reflecting the training of the medicinal chemists involved. Apparently the generation of leadlike solutions helped the medicinal chemists to select good starting points for future lead optimization, away from existing compound libraries.

unactivated pyridines via multiple C(sp3/sp2)–H functionalizations of a methyl, hydroxymethyl, or aldehyde group has been developed providing a general access to all four azafluorenones. The application of this protocol is further demonstrated to the synthesis of azafluorenone related fused nitrogen heterocycles and fluorenones. In addition, design and synthesis of a novel fluorene based organicemitter for

4-(hydroxymethyl)phenylboronic acid for the synthesis of substituted biarylmethanols in water. However, substrates are limited to the aryl bromides and activated aryl chlorides. To date, there is no report that investigates the Suzuki reaction of chlorophenylmethanol in water. As a continuation of our interest in the synthesis of biarylmethanols, we have prepared a newphosphine adduct of palladacycle 2 from the
