Thiadiazoles undergo substitution reactions reflecting their relatively high aromatic character but in contrast the 1,2,5-thiadiazole 1-oxides and 1,1-dioxides suffer addition chemistry supporting their non- or antiaromatic characters. 

From a chemosystematic point of view, it is interesting to note that prenylated flavonoids such as microfolione (56) have been found in a species of the family Ptaeroxylaceae, because the relationships of this family with other families were disputed in the past. Most taxonomists considered the Ptaeroxylaceae closely related to families in the order Rutales to which the Rutaceae and Meliaceae belong, whereas others considered it related to the Sapindaceae. Flavonoid chemistry supports a close relationship to the Rutaceae and Meliaceae, as iso-prenylated flavanones also occur in these families, e.g., 58 and 98 in Boronia coerulescens ssp. spinescens, the farnesyl-bearing 121 (Figure 15.3) in B. ramosa (Rutaceae)," and flowerine (59) and flowerone (60) in Azadirachta indica (Meliaceae). Microfolione is one of the few new flavanones for which the (2i )-configuration has been determined.

Dedicated microwave reactors have been developed that are capable of reliable and safe operation with volatile organic solvents at elevated temperatures andpressures13,65,91-95. Independent investigations into optimal parameters for microwave chemistry support this approach90,96. 

Long-term side effects of lithium treatment include weight gain. The treatment is associated with development of hypothyroidism in about 10-15% of cases. There is an association with kidney disease. Birch has expressed the general view that Li may interact with magnesium-dependent processes, and theoretical chemistry supports this view. Despite the widespread clinical significance of Li, there is presently no consensus on its mode of action. One postulate for the mechanism is termed hyperpolarization . Li affects the conductivity in cell transport channels. Other explanations include modulation of neurotransmitter concentrations and inhibition of Na+/K+/Mg2+/ Ca2+ ATPases.

Chemistry support is frequently needed to measure the residues of possible toxic substances such as pesticides in each lot of test organisms before they are used in toxicity tests. The analysis should be extensive enough that the data will document any residues that might interfere with the usefulness of the test.

The applications highlighted in this section focus mainly on medicinal chemistry support. A review by Burdick and Stults indicates that a similar methodology may be adapted for the analysis of peptide synthesis products, using ESI-MS techniques (Burdick and Stults, 1997). The application of LC/MS for peptide analysis is similar to the previously described schemes for chemical synthesis and purification and focuses on confirmation of the desired peptide and identification of synthetic by-products.
