The Unglamorous Half: solubility is a real problem

Two compounds in this family exist for a reason nobody writes press releases about — the parent barely dissolves.

The problem

Several of the parent scaffolds are poorly soluble. A compound that cannot be dosed is not a therapy regardless of what it does in a dish, and a great deal of promising in-vitro work dies exactly here rather than at the mechanism.

The design

A PEG3 solubilising ester, cleaved to release the parent. Two compounds deposited. There is no new biology in this family at all — it is formulation chemistry published alongside the rest so that the series is usable rather than merely interesting.

Why it is in the journal

Because leaving it out would misrepresent what the work is. A compound series that publishes only its exciting members is advertising. The delivery prodrugs are the part that says somebody intends these to be made.

From engineering drawings to molecular blueprints.

One discipline runs underneath all of it: computational engineering — designing the thing completely, and proving out what you can, before anyone cuts metal or runs a reaction. It is the same craft whether the object is a bracket or a molecule. Only the units change.

AutoCAD engineering

Concept geometry, stage views and engineering drawings — a question turned into something you can inspect and measure. Fabrication readiness still requires validation.

02

Structure and materials

The lattice between the two worlds: geometry that has to obey physics before it is worth costing, let alone building.

03

Biotechnology & molecular research

The same discipline applied to chemistry — scaffolds, conjugates and the design rationale for why a given structure should be made before anyone makes it.

04

Full RDKit molecular blueprints

Every structure parsed, sanitised and reported with its computed property set: isomeric SMILES, mass, lipophilicity, polar surface area, stereocentres. Computed, never quoted.

Our intention is plain: to own this field — computational engineering from the drawing to the molecule. Not by holding patents, but by being the group that does the work in the open, publishes its own corrections, and is the best in the world at deciding what is worth building next.

Computational designs only. Nothing described here has been synthesised, assayed or administered, and every property is a computed descriptor rather than a measurement. Fabrication and clinical readiness require validation that happens outside this factory.
