From a chemical perspective, penicillins have a [beta]-lactam ring attached to a thiazolidine ring with one side chain. IgE-mediated penicillin allergy (type I allergic reaction) is likely to include all [beta]-lactam ring-containing antibiotics.
According to the electrostatic relay model, cAMP interacts with R209 side chain and forces D170 to switch from R226 to R209.
The drug is a modification of the saligenin albuterol, with a long nonpolar (i.e., lipophilic) N-substituted side chain. Salmeterol thus consists of a polar, or hydrophilic, phenyl ethanolamine "head," with a large lipophilic "tail" or side chain.
Our calculations demonstrate that the SWNT-PFO binding energy tends to increase as the length of the side chain increases reaching the optimal value for octyl groups.
Flydrophobicity is one key advantage provided by the long aliphatic side chain present in CNSL.

The syntheses of A, B, and C are shown in Scheme 1(a), and their side chain contents are shown in Table 1.
(8) The general synthetic routes to 1 provided the first chemical basis for systematically correlating its unusual side chain structure with biological functions.
Vitamin K2 is a group of compounds collectively referred to as menaquinones, which are classified according to the number of isoprenyl units on the side chain. Thus, vitamin K2 with 4 isoprenyl units is called menaquinone-4 (MK-4; also known as menatetrenone), and vitamin K2 with 7 units is called menaquinone-7 (MK-7).
