User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is propane-1,3-diamine in which a hydrogen attached to one nitrogen is substituted by a 3-aminoprop-1-yl group, and a hydrogen attached to the other nitrogen is substituted by a 4-aminobut-1-yl group. A polyamine natural product, its name arises from its similarity to spermine and the fact that it was first isolated from the extreme thermophile, Thermus thermophilus. It is a polyazaalkane and a tetramine. It is a conjugate base of a thermosperminium(4+).
