Fluoroacetamide (FAM) is a small (77 Da) and highly toxic chemical, formerly used as a rodenticide and potentially as a poison by terrorists. Poisoning with FAM has occurred in humans, but few reliably rapid detection methods and antidotes have been reported. Therefore, producing a specific antibody to FAM is not only critical for the development of a fast diagnostic but also a potential treatment. However, achieving this goal is a great challenge, mainly due to the very low molecular weight of FAM. Here, we design two groups of FAM haptens for the first time, maximally exposing the fluorine or amino groups, with the aid of linear aliphatic or phenyl-contained spacer arms. Interestingly, whereas the hapten with fluorine at the far end of the hapten did not induce an antibody response to FAM, the hapten with an amino group at the far end and phenyl-contained spacer arm triggered a significantly specific antibody response. Finally, a monoclonal antibody (mAb) named 5D11 was successfully obtained with an IC50 value of 97 μg mL?1 and negligible cross-reactivities to the other nine functional and structural analogs.

Page/Page column 67, (2008/12/07)
The present invention pertains generally to the field of therapeutic compounds, and more specifically to certain aryl sulfonamides and related compounds (collectively referred to herein as "BPSAAA compounds"), as described herein, and including, for example, biphenyl-4-sulfonic acid (hydroxyalkyl-phenyl)-amides and related compounds. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, in treatment and/or prevention, for example, of inflammation and/or joint destruction and/or bone loss; of disorders mediated by excessive and/or inappropriate and/or prolonged activation of the immune system; of, inflammatory and autoimmune disorders, for example, rheumatoid arthritis, psoriasis, psoriatic arthritis, chronic obstructive pulmonary disease (COPD), atherosclerosis, inflammatory bowel disease, ankylosing spondylitis, and the like; of disorders associated with bone loss, such as bone loss associated with excessive osteoclast activation in rheumatoid arthritis, osteoporosis, cancer associated bone disease, Paget's disease and the like.
