calculations. Propyl and butyl group substituted indigo was most soluble in chloroform and 1,2-dicrolobenzene, and these solubility were 65–89 times increased as compared to the parent indigo. DFT calculations suggested that the presence of the alkyl chains at the 5.5′-position increases the energy of the highest occupied molecular orbital, while reducing the energy of the lowest unoccupied molecular orbital

populations of receptors. Examination of a series of 5-(alkyloxy)tryptamine derivatives demonstrated that compounds with unbranched alkyl groups of up to eight carbon atoms bind with high affinity at human 5-HT1D beta receptors (Ki < 5 nM) but demonstrate less than 50-fold selectivity relative to 5-HT1A receptors. Alkyl groups longer than eight carbon atoms impart reduced affinity for 5-HT1A receptors whereas
