1H n.m.r.

Because Jed and Jef were both 9Hz, He corresponded to a sextet at d 5.54 with Jeg 2 Hz. The methylene protons Hf and Hg gave signals at d 2.66 and 1.9, respectively. (Ref. 0016) |

A couple of methods for partial synthesis. Prepare the 16-ketone of cinobufagin, reduce 14,15b-epoxide group with chromous acetate to yield b-hydroxy ketone and a,b-unsaturated ketone. Selectively reduce the b-hydroxy ketone with Urushibara nickel A to produce alcohol, which is acetylated to provide diacetate. Treat the diacetate with HCl in methanol to give bufotalin. Alternatively reduce first the a,b-unsaturated ketone with Urushibara nickel A to allylic alcohol. After acetylation subject the olefin to hypoiodous acid or hypobromous acid, then treat the resulting halohydrin with Urushibara nickel A. Hydrogenolyze the product to bufotalin 3b-acetate.

Adrenocortical steroid regulates matabolism of electrolyte and water. Synthesized in zona glomerulosa, transported by albumin. Secreted 400mg/day in human male adult. The secretion is influenced by ACTH, GH, plasma sodium/potassium ions, and renin-angiotensin system, which induces resorbing of sodium, chloride, bicarbonate ions and potassium ion from uresis. Activity can be detected at the dose of 0.05-0.01mg in rat urinary sodium retention assay. 16mg Desoxycorticosterone acetate must be needed to retain the same activity. (Ref. 0579) |

However they are proved to be identical compound by acetylation: shift of m.p. to 211-212 C, [a]26/D= +90 and +92 (in alcohol), respectively. Dehydrogenation of equilin glycol yields 7-ketoestrone, which turns to be 7-hydroxy-estrone by reduction. (Ref. 0087) |

Ppt with cholesterol. Escin can be separated into two isomers, a-escin and b-escin, because of different properties in melting point, optical rotation, hemolytic index, solubility in water. (Ref. 0805) Escin had ever been regarded as an glycoside from aescigenin (C30H48O5). Isolation and purification by chromatography. (Ref. 0811/0812/0813) Escin is a mixture of two major Glycosides. The aglycon is protoescigenin, which is acylated at C-22 with acetic acid. The sugar parts are composed of Glucuronic acid and two D-Glucose molecules. The difference in two main glycosides is based on acylated compound at C-21, angelic acid or tiglic acid. Hydroxyl group at C-3 is linled to D-glucuronic acid, which is connected to 2 molecules of D-glucose at 2, 4-positions. One of D-glucose molecules is often substituted with D-xylose or D-galactose.

In the lavator ani test by Eisenberg and Gorgan for anabolic activity as well as weight increase in seminal vesicle and ventral prostate for androgenic activity, along with testosterone propionate as the standard, among 17-alkyl-19-nortesto-sterone compounds tested, 17-ethyl-19-nortestosterone shows high anabolic activity and relatively low androgenic activity (1/16 of testosterone propionate), so that possible most applicable to medication. In oral ingestion to rats, this compound is at least 5-times higher anabolic activity than 17-methyltestosterone and 19-nortestosterone. 17-Ethyltestosterone, not 19-noranalog, is very weak anabolic agent.

In vitro biosynthesis of tetrahymanol: lyophilize T. pyriformis, suspend in Ringer phosphate medium and break in Potter-Elvehjem homogenizer, and added[14C]-squalene and [3H]-squalene 2,3-oxide.In the homogenate, squalene can be directly converted to tetrahymanol. Squalene-2,3-oxide is not the intermediate. The enzyme system holds the biosynthetic activity after lyophilization. There seems to be no interconversion between squalene and squalene-2,3-oxide. The oxygen molecules of tetrahymanol might not be derived from atmosphere. (Ref. 1105) The enzyme system involving in biosynthesis was soluble and isolated in cell- and lipid free-system. Downstream reaction from squalene, the system requires no oxygens, hydrohen at C-3 and oxygen at C-21 are from medium. (Ref. 1104) Tetrahymanol from T. pyriformis can be substituted with ergosterol. This is because ergosterol blocks the synthesis of tetrahymanol. (Ref. 1103) Inhibition of tetrahymanol biosynthesis by cholesterol.
