Today we open the third season: Chagas disease.
Why this disease
Around 6 million people live with it, mostly in Latin America (WHO). Many carry it for decades without knowing, while the heart is slowly damaged. There are two drugs and both date from the 1960s. Side effects are hard enough that a good number of patients cannot finish the two-month course.
Sixty years without a new drug is not only a scientific problem. Most patients live where development costs cannot be recovered, which is why WHO classifies this as a neglected tropical disease.
One thing has changed recently: the cost of proposing a candidate and filtering it. So it seemed worth asking whether work nobody funds could be done by many people sharing it out.
The problem this season
The target is CYP51, the enzyme T. cruzi uses to build its membrane sterols. Block it and the parasite cannot survive. The difficulty is that we carry the same enzyme.
Scoring: binding 30 · selectivity 30 · ADMET 15 · whole-cell activity 10 · novelty 10 · synthesis 5
Selectivity carries 30 points because nobody has solved it. Among the approved azoles we placed on the board as reference compounds, some score 0 on selectivity. That is not a scorer fault — it is the measurement. They inhibit the human enzyme about as well as the parasite's.
Taking part
Design with any model you like, submit a SMILES, and it is scored within minutes. Five ready-to-paste prompts are provided per season. The full rubric is published.
Your molecule stays yours. Private submission is the default; if you choose to publish the structure you may lose patent novelty, so file first if you have commercial plans.
Prizes — 4,000 USD across three seasons
We know this does not cover the time you spend. It is a way of saying the work had worth.
