Cell-cycle arrest and cell-cycle escape in cancer 🎗️

Cell-cycle arrest is not the same as long-term tumour control.

That difference matters in patients.🧑‍🤝‍🧑

After treatment, cancer cells can follow two paths.

🧬 Cell-cycle arrest
Cells stop dividing.
They remain alive.
Scans often look reassuring 📊

🧬 Cell-cycle escape
Cells adapt.
Division slowly returns.
Resistance builds quietly ⚠️

This gap is easy to miss.

During my PhD, I observed clear cell-cycle arrest in cancer cells after FEC chemotherapy 🧪💊.

Growth stopped.

Cells survived.🧫

Early responses looked convincing.

With time, some cells adapted despite treatment.

That experience changed how I interpret “stable disease.”

Scans show size.

Biology shows intent 🔬

Escape often begins long before progression appears.

What this means clinically 🏥:

Stable scans do not always reflect stable biology

Early biological changes matter

Timing can shape long-term outcome
👇
What early biological shift signals that control may not be durable?

Understanding NMR Spectroscopy and Chemical Shift Ranges for Functional Groups

Nuclear Magnetic Resonance ( NMR ) spectroscopy is one of the most powerful analytical tools in pharmaceutical chemistry. It helps chemists determine the structure, purity, and chemical environment of molecules by analyzing the behavior of nuclei (commonly ¹H or ¹³C ) when exposed to a strong magnetic field. In proton NMR ( ¹H-NMR ), the chemical shift (δ, in ppm) provides information about the type of hydrogen atoms present in a compound and their surrounding electronic environment. Depending on nearby atoms and functional groups, signals appear in specific regions of the spectrum — often referred to as upfield (shielded, lower δ values) or downfield (deshielded, higher δ values). The image above summarizes the characteristic δ ranges for different functional groups in ¹H-NMR. Let us break it down systematically: 1. Downfield Region (δ 12 – 6 ppm) Hydrogens in this region are strongly deshielded due to electronegative atoms or π-bond systems. Carboxylic Acids (–COOH) : δ 1...

Pushing the boundaries of computational drug discovery at Isomorphic Labs

The Isomorphic Labs Drug Design Engine (IsoDDE) has unlocked a new frontier in in-silico drug design, representing a significant evolution beyond AlphaFold 3. What IsoDDE delivers: 🔹 Massive accuracy leap on unconstrained structure prediction The engine more than doubles AlphaFold 3's accuracy on extremely challenging protein-ligand prediction tasks — including systems far outside the training distribution. 🔹 Best-in-class binding affinity prediction IsoDDE predicts how strongly small molecules bind to targets with accuracy that exceeds gold-standard physics-based methods, at a fraction of the computational cost and time. 🔹 Blind identification of novel binding pockets Even without existing structural data, the engine reveals previously unseen binding sites — just from an amino acid sequence — enabling drug designers to explore entirely new chemical action spaces. 🔹 Expanded support for complex biologics Beyond small molecules, the engine boosts prediction fidelity for...
