Converter for chemical energies | Conversion between kJ/mol and kcal/mol chemical energy units. |
PRODRG | Server will convert coordinates for small molecules in PDB format to the following topology formats: GROMOS, GROMACS, WHAT IF, REFMAC5, CNS, O, SHELX, HEX and MOL2. In addition, coordinates for hydrogen atoms are generated. |
Property Explorer | Allows drawing chemical structures and calculates solubility, drug-likeness properties. |
SwissADME | Compute physicochemical descriptors as well as to predict ADME parameters, pharmacokinetic properties, druglike nature and medicinal chemistry friendliness of one or multiple small molecules to support drug discovery. |
chemicalize.org | ChemAxon's Name to Structure parsing to identify chemical structures on webpages and other text. |
eMolecules | Chemical structure search by drawn structural models. |
