Objectives
Objectives in this puzzle are driven primarily by the evaluation criteria used by CACHE.
Maximum bonus: +8 000
Torsion Quality (max +1000)
Keeps bond rotations in a good range. Using Wiggle or Tweak Ligand can fix bad torsions. (Show highlights torsions to be rotated.)
Number of Rotatable Bonds (max +1000)
Intended to keep the ligand from getting too big and floppy. You can reduce rotatable bonds by deleting groups or forming rings. (Show highlights rotatable bonds.)
Ligand TPSA (max +1000)
Topological Polar Surface Area - Keeps the polar surface area (including buried polar surface) low. To improve, try removing oxygens and nitrogens. (Show highlights atoms contributing to higher TPSA.)
Ligand cLogP (max +1000)
A measure of polarity - Keeps the molecule from getting too hydrophobic. To improve, try adding polar oxygens and nitrogens. (Show highlights atoms contributing to higher cLogP.)
Fraction of four-bonded carbons (max +1000)
Measures how carbons with bonds to four atoms ("sp3 hybridized") there are. Too few (too many double and triple bonded carbons) is bad. (Show highlights carbon atoms at issue.)
Bad Groups (max +1000)
Gives a bonus for avoiding groups that interfere with assays, or which are far from the compounds in the library. (Show highlights groups at issue.)
Molecular Weight (max +1000)
Keeps the ligand a reasonable size.
Synthetic Accessibility (max +1000)
Keeps the ligand from going too far from the compounds in the library. (Show highlights parts of the molecule at issue.)
