The core of the molecule is a benzene ring (numbered C1-C6).

C1 is attached to a quaternary sp3 carbon (no stereochemistry specified). This carbon is further bonded to:
  - an iodine atom,
  - a methyl group (-CH3),
  - a thiol group (-SH).

C3 bears a methylene, -CH2-, which is connected to an imine nitrogen. The N is doubly bonded to an sp2 carbon that carries  
  - a hydroxyl group (-OH) and  
  - a vinyl group (-CH=CH2).  
The overall side chain at C3 can be represented as -CH2-N=C(OH)-CH=CH2, with no stereochemistry defined for the double bond.

C4 is directly bonded to a tertiary amine nitrogen, which bears:
 - a methyl group and
 - an iodine atom.

No other substituents are present.
