Complex Natural Product Structures (Strychnine, Morphine, Paclitaxel)
Even densely fused natural products such as strychnine, morphine and paclitaxel can be called up by name or SMILES, complete with stereochemistry. Each is captioned with its formula and molecular weight.

Features used in this figure
- Structures from names, CAS numbers or SMILES (PubChem)
- Wedge and hash stereobonds
- ACS style (bond length and line width)
- Captions with subscripted formulas and molecular weight
- Properties fetched from PubChem
How to draw it in FlaskConnect
- Type a name (for example strychnine) or a SMILES string into “Add structure”.
- Use “Fetch properties” to add the name, formula and molecular weight from PubChem as a caption.
- You can also look up the name of a structure you drew in the editor.
- Rotate or flip to tidy the orientation; wedges and hashes stay correct.
Notation tips
- A wedge points toward the viewer and a hash away. The number of stereocenters: strychnine 6, morphine 5, paclitaxel 11.
- Write molecular formulas in Hill order: C, then H, then the other elements alphabetically.
- Add (R) or (S) to the name to tell enantiomers apart, for example (S)-naproxen.

Draw this in the app
This figure was drawn in FlaskConnect. Call up structures by name or SMILES, and add lone pairs, curved arrows and arrow text (subscripts and superscripts with buttons) in place. Drawing structures and schemes is Pro (US$3.99/month, first month free, or US$39.99 once); apparatus drawing and export are free.
