Two syntheses of the bioactive small molecule (+)-imperanene (197), isolated from Imperata cylindrica, demonstrate that intra- and intermolecular carbenoid C-H insertion can be used as two different means to the same end. The Doyle group reported an intramolecular approach toward this natural product, with diazoester 198 as the cyclization precursor (Scheme 49, top) [140], In the key event, Rh2(4S -MPPIM)4-catalyzed carbenoid insertion led to lactone 199 in 68% yield and 93% ee. Other rhodium catalysts were found to give inferior yields and enan-tioselectivities. Elaboration of 199 to (-i-)-imperanene provided the natural product in 12 steps and approximately 16% overall yield. 

To expand our understanding of the anti-inflammatory activity of the well-known oleanolic acid isolated from one of its best characterised sources, the seeds of Luffa cylindrica (Cucurbitaceae), a series of experiments were performed to correlate complement activity with the inflammation caused by both carrageenan and Freund s adjuvant, in presence and absence of oleanolic acid and ibuprofen, which were administered at 60 mg/kg i.p. It was concluded that the effect of this triterpenoid must be mediated by its anti-complementary activity 73]. An analogous conclusion was drawn regarding the activity of boswel ic acids in the same tests [74]. 

Alanine appears to be formed primarily by alanine dehydrogenase in A. cylindrica, C. licheniformey P. boryanumy and A. nidulanSy because the inhibition of formation of glutamate and glutamine by methionine sulfoximine is not accompanied by a comparable inhibition in the formation of alanine (Table I). Moreover, alanine formation by these species was not reduced in the presence of aminooxy acetate, an inhibitor of amino transfer reactions (I3,J4). However, in A. variabilis alanine appears to be formed by a transamination reaction, because synthesis of [ N]alanine from was strongly inhibited in the presence of... 

The effect of the water content of a thallus on net photosynthesis has been noted earlier. Ried (1960b) showed that for Umbilicaria cylindrica the optimum rate was at 65% saturation but this was reduced by half when the thalli were fully saturated. He found, however, that in more loosely organized thalli, i.e., those without lower cortices (Peltigera) or with cyphellae(5ncra), photosynthesis was most rapid at 90% saturation with only a small decline above this level. He felt the decline was due to the difficulty of gas exchange in fully saturated leathery thalli such as Umbilicaria. However, the findings of Kershaw and Rouse (1971) with Cladonia alpestris, which has a hollow tubular thallus, casts doubt on this.
