the rhizosphere as well as in planta. However, its biological activity is yet to be evaluated, due to its relative chemical instability and its low natural abundance. Herein, we describe the gram‐scale synthesis of heliolactone and its derivatives by using Stille cross‐coupling as the key bond‐forming reaction, and we disclose some of their biological activities (soil stability, binding ability to strigolactone

A composition and method for influencing energy metabolism and treating metabolic and other disorders is provided. A terpenoid lactone that is a selective activator of SIRT1 is generally in the form of a terpenoid dilactone having a 5-alkenyloxy-furan-2- one group, such as strigolactone, GR 24, or another strigolactone analog, and is used as a therapeutic agent in a method for influencing energy metabolism and treating metabolic and other disorders. The terpenoid lactone may be administered as an individual agent or combined with a second compound such as a flavonoid, chalconoid, tannin, or nicotinamide inhibition antagonist.

The oxofuryl ester derivatives of 6-(.alpha.-amino-phenylacetamido)penicillanic acid, 7-(.alpha.-aminophenylacetamido)-cephalosporanic acid, or 7-(.alpha. -aminophenylacetamide)desacetoxycephalosporanic acid represented by the general formula ##SPC1## Wherein A represents ##SPC2## Wherein R.sup.1 and R.sup.2, which may be the same or different, each represents a hydrogen atom or a lower alkyl group, said R.sup.1 and R.sup.2 may form together a 1,3-butadienylene group, R.sup.3 represents a hydrogen atom or an acetoxy group, and Means a single bond or a double bond, and acid addition salts of them. When those compounds are orally administered, they are readily absorbed by the intestines and show antibacterial activity by splitting their ester bonds. The rate of absorption of the compounds by the intestines are higher and the toxic property of them is less than those of known compounds similar to the above compounds.
