Abstract:
A series of 3-demethoxycarbonyl-3-carbamate methyl anhydrovinblastine derivatives (compounds 8b-32b) were designed, synthesized, and evaluated for their inhibition activities against human non-small cell lung cancer cell line (A549) and a human cervix epithelial adenocarcinoma cell line (HeLa). The structure-activity relationships of this new series are described in this paper. Cytotoxicity data revealed that the size of substituents and substitution position had important influence on cytotoxic activity. On two cell lines, compounds (8b and 30b) had more potent cytotoxic activity than the lead compound (1e, AVLB). The preliminary antitumor studies of 8b in vivo showed that it might be promising for the development of new antitumor agents.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
