Inhibitors continued organic

Somehow, Seebach ends his superb review, in which more than 500 references are quoted, with a rather optimistic message "that organic synthesis continues to react forcefully and with vitality to new challenges, still ready to pursue old dreams", and he refers to some exciting new targets such as supramolecular structures inhibitors, suicidal substrates and flustrates monoclonal antibodies and... 

The corrosion inhibitor can also be a redox couple presenting a reversible and fast electrochemical behavior that is able to react in place of the metal. This is obtained when its redox couple potential is lower than that of the considered metal. The reversible behavior allows the continuous regeneration of the corrosion inhibitor. These reducing agents are often organic compounds soluble in aqueous solutions. A nonexhaustive list is given in Ref. [5]. 

The test kit is based on immunoassay techniques and the method takes about 10 minutes to provide an analysis. A unique tag, permanently attached to the polymer, changes the color of special test strips exposed to ppm levels of polymer. The strips indicate the amount of tagged polymer that is present, without interference from other additives and contaminants. This technology is not currently available for continuous inhibitor detection, but given the importance of AH Organic Programs, there is little doubt that further developments will take place. The Water Additives Division of Great Lakes Chemical Corp. have also recently introduced a similar simple and accurate immunoassay test for the detection of Belclene 200 antiscalent. 

Keratin IFs exhibit different motile behaviors compared with type III and IV IFs, and continue to move in the absence of MT in cells treated with MT inhibitors, such as nocodazole. It has been proposed that actin may be involved in their transport (Yoon et al., 2001). Time lapse imaging of keratin-GFP has revealed that keratin IF formation begins in the cell cortex in a region enriched in actin and required for both intact MT and actin, and that actin governs the organization and movement of keratin in Xenopus egg extracts (Weber and Bement, 2002). Less is known about specific mediators of these interactions, although the fact that myosin Va associates with NFs raises the interesting possibility that other such interactions may exist for keratins. 

In 1982 Ayerst Laboratories in Montreal became the first company in Canada to install a commercial software tool (the SYBYL suite from Tripos Associates) to help in the development of pharmacophoric models from structure-activity relationships. The installation of the software was the second ever, worldwide, by a company and is a testimonial to the foresight of the director of medicinal chemistry, Dr. Leslie Humber, for having championed its installation. Dr. Adi M. Treasurywala, then an organic chemist with some experience in medicinal chemistry, became the first industrial computational chemist in Canada that year. The use of modeling approaches contributed in a minor but significant way to the discovery of the compound known as Tolrestat, which was an inhibitor of lens aldose reductase. This led to the acknowledgment of Treasurywala as a coinventor of the drug on several patents that were filed in this research area. Approximately in 1983, Ayerst closed down its discovery effort in Canada and moved to Princeton, New Jersey, where an expanded effort in the area of computational chemistry continues.
