, p. 7435 - 7450 (1995)
Three drimanes, polygodial (2), albicanyl acetate (3) and 7-oxo-8,12-drimen-11-al (5), and two homodrimanes, 13,14,15,16-tetranorlabd-7-en-12,17-dial (6) and 7-oxo-13,14,15,16-tetranorlabd-8(17)-en -12-al (7), were synthesized from (-)-sclareol (1), and their antifeedant, antitumor and antimicrobial properties tested. In most cases, 6 and 7 were found to be more active than 2.

The enantiospecific synthesis of drimenyl acetate (8), a key intermediate in the synthesis of biologically active drimanes, and albicanyl acetate (14), potent fish antifeedant, from sclareol (1), are described.Also a short and efficient synthesis of polygodial (22), from albicanyl acetate (14), is shown.

Okuda, Roy K.,Scheuer, Paul J.,Hochlowski, Jill E.,Walker, Roger P.,Faulkner, D. John
, p. 1866 - 1869 (1983)
Sesquiterpenes of the drimane series were isolated from eight porostome nudibranchs.A mixture of polygodial (1) and olepupuane (3), a new sesquiterpene diacetate, was obtained from Dendrodoris nigra, Dendrodoris tuberculosa, and Dendrodoris krebsii.Olepupuane (3) and the sesquiterpene esters 5 were found in Doriopsilla albopunctata, Doriopsilla janaina, and an undescribed yellow porostome, although one collection of Doriopsilla albopunctata contained only olepupuane (3) while a second collection contained a related methoxy acetal 4.Two undescribed porostomes contained only the sesquiterpene esters 5 found previously in Dendrodoris limbata.The structures of olepupuane (3) and the methoxy acetal 4 are based on interpretation of spectral data.

, (2021/03/13)
In one aspect the invention relates to a method of treatment selected from the group consisting of: (a) treating a symptom such as pain in a subject identified or diagnosed as having Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS); (b) treating a symptom such as pain in a subject having dysfunctional TRPM3 ion channel activity; (c) restoring NK cell function in a subject having dysfunctional TRPM3 ion channel activity; and (d) restoring calcium homeostasis in a subject having dysfunctional TRPM3 ion channel activity. The method comprises the step of administering to the subject a therapeutically effective amount of at least one therapeutic compound selected from the group consisting of: (i) an opioid receptor antagonist; (ii) an opioid antagonist; and (iii) a therapeutic compound that restores TRPM3 ion channel activity. In some embodiments the therapeutic compound is naltrexone hydrochloride.
Diastereoselective ring - Opening of 12-acetoxy-9α and 9β(11)-epoxy-7-drimene: Homochiral semisynthesis of poligodial and warburganal

, p. 3781 - 3784 (2007/10/02)
Starting from a zamoranic acid derivative (Methyl 15-tetrahydropiranyloxy-7-labden-17-oate) poligodial and warburganal have been synthesized in several steps with a 55% overall yield and 27% overall yield, respectively.
Chemistry of zamoranic acid. Part V. Homochiral semisynthesis of active drimanes: Pereniporin B, polygodial and warburganal

, p. 10995 - 11012 (2007/10/02)
Methyl 14,15-dinor-13-oxo-7-labden-15-oate was obtained from zamoranic acid methyl ester. The former by photochemical cleavage yielded methyl 7,9(11)-drimadien-12-oate, whose chemoselective epoxidation afforded methyl 9α,11-epoxy-7-drimen-12-oate, which is the key synthetic precursor for pereniporin B, polygodial and warburganal.
AN ALTERNATIVE PARTIAL SYNTHESIS OF (-)-POLYGODIAL
Razmilic, Ivan,Lopez, Jose,Sierra, Jorge,Cortes, Manuel
, p. 95 - 104 (2007/10/02)
A four steps partial synthesis of (-)-polygodial (1) has been achieved, using (-)-drimenol (2) as starting material.
SYNTHESIS OF BOTH THE ENANTIOMERS OF POLYGODIAL, AN INSECT ANTIFEEDANT SESQUITERPENE
Mori, Kenji,Watanabe, Hidenori
, p. 273 - 282 (2007/10/02)
Both the natural and unnatural enantiomers of polygodial, an insect antifeedant sesquiterpene of the drimane family, were synthesized starting from (S)-3-hydroxy-2,2-dimethylcyclohexanone as a single chiral source.
Oxo Complexes of Ruthenium(VI) and (VII) as Organic Oxidants
Green, Graham,Griffith, William P.,Hollinshead, David M.,Ley, Steven V.,Schroeder, Martin
, p. 681 - 686 (2007/10/02)
Oxidation of a variety of saturated and unsaturated primary and secondary alcohols by tetraoxoruthenate(VI), 2-, tetraoxoruthenate(VII), -, barium trans-trioxodihydroxoruthenium(VI), trans-Ba, dioxotrichlororuthenate(VI), -, and dioxodichlorobipyridylruthenate(VI),, has been studied; 2- may be used catalytically in conjunction with 2- under basic aqueous conditions.For some of these systems, the oxidation of several aldehydes and amines were also examined.Both 2- and - oxidise primary alcohols to carboxylic acids and secondary alcohols to ketones; the reactivity of these reagents towards unsaturated alcohols was studied in particular.The new species and also cleanly oxidise a wide range of alcohols to aldehydes and ketones without attack of double bonds.Ba functions as a heterogeneous oxidant in dichloromethane, oxidising only the most reactive alcohols to aldehydes.

Guillerm, D.,Delarue, M.,Jalali-Naini, M.,Lemaitre, P.,Lallemand, J.-Y.
, p. 1043 - 1046 (2007/10/02)
The three possible isomers of polygodial, epimers at C-9, cis and trans fused, are described.Controlled kinetic and thermodynamic epimerizations allow preparation of all stereoisomers from the same key intermediate.
