Borrowing an idea from Randall Munroe

Generative models have emerged as potentially powerful methods for molecular design, yet challenges persist in generating molecules that effectively bind to the intended target. The ability to control the design process and incorporate prior knowledge would be highly beneficial for better tailoring molecules to fit specific binding sites. In this paper, we introduce MolSnapper, a novel tool that is able to condition diffusion models for structure-based drug design by seamlessly integrating expert knowledge in the form of 3D pharmacophores. We demonstrate through comprehensive testing on both the CrossDocked and Binding MOAD data sets that our method generates molecules better tailored to fit a given binding site, achieving high structural and chemical similarity to the original molecules. Additionally, MolSnapper yields approximately twice as many valid molecules as alternative methods.

Among the smaller substituents in the medicinal chemist’s toolbox, the hydroxy (OH) group can bestow one of the largest impacts in the drug-like properties of a molecule. A previous study showed that an H-to-OH structural modification effectively decreases lipophilicity, increases solubility, and decreases hERG inhibition. Despite these benefits, an OH group is not always recommended in drug molecules because it presents a metabolic “soft spot” for oxidation and glucuronidation in primary and secondary alcohols. Furthermore, the OH group presents challenges in permeability. In contrast, tertiary alcohols (3° ROH) often display an improved metabolic profile because oxidation at the 3° ROH is not possible, and the geminal alkyl groups could sterically shield the OH group from glucuronidation and permeability challenges. Through a series of matched molecular pairs, this Perspective highlights the 3° ROH as a motif that can reap the benefits but minimize the drawbacks of hydroxy groups in drug discovery.

I visited San Diego last week and have opportunity to discuss with lots of researchers. It was really a great experience for me. And I could get positive feedback from my blog post. BTW, Sometime medicinal chemist try to conbine positive transformation for compound optimization. For example adding Cl atom to phenyl ring improve potency of comound A (it's comound B) and replace carbon atom to nitrogen improve potency of compound (it's compound C), next we would like to add Cl atom and replace carbon atom to nitrogen to generate compound D.
