Abstract

A novel glycoside of an insect-metamorphosing substance, ponasteroside A, has been isolated from Pteridium aquilinum var. latiusculum (Pteridaceae). Chemical and physico-chemical properties of ponasteroside A and its hexaacetate (IV) and, in particular, its enzymatic hydrolysis into ponasterone A (II) and glucose have established the structure and absolute configuration of ponasteroside A as represented by formula 1.

Chemometric guided isolation of new triterpenoid saponins as acetylcholinesterase inhibitors from seeds of Achyranthes bidentata Blume
2024, Fitoterapia
Achyranthes bidentata Blume (Amaranthaceae) is an annual or perennial herb widely used as ethnomedicine in Traditional Chinese Medicine for treating fever, cold, ulcers, mensural pain, dementia, and osteoporosis. In the current study, UPLC-IM-Q-TOF-MS/MS-based chemometric approach was adopted for the tentative identification of fifty-six compounds in the extract and fractions of A.bidentata seeds. Further, the chemometric-guided isolation led to the isolation of two previously undescribed oleanane-type triterpenoid saponins, named achyranosides A-B (27 and 30), along with three known compounds (31, 44, and 23) from water fraction of A. bidentata seeds. The structures of new compounds were elucidated based on the detailed analysis of NMR, HR-ESI-MS, FT-IR spectral data, and GC-FID techniques. The isolated compounds in vitro acetylcholinesterase inhibitory activity revealed the promising activity of chikusetsusaponin IVa (23) (IC₅₀ = 63.7 μM) with mixed type of AChE inhibition in enzyme kinetic studies. Additionally, in silico binding free energy of isolated compounds disclosed the greater stability of enzyme-ligand complex owing to underlying multiple H-bond interactions. Overall, the study demonstrates the effectiveness of a chemometric-guided approach for the phytochemical exploration and isolation of new oleanane-type triterpenoid saponins from A. bidentata seeds.
The metabolism of <sup>3</sup>H-molting hormone in Calliphora erythrocephala at the mature larval and white puparial stages
1976, Insect Biochemistry
³H-metabolites extracted from whole insects after injection of ³H-α- or ³H-β-ecdysone were separated by thin layer chromatography and quantified by scintillation counting. Chromatographic peaks in order of polarity are: ³H-α-ecdysone, ³H-β-ecdysone, a metabolite with mobility similar to 26-OH-β-ecdysone, and a group of very polar metabolites which include glucose and sulfate conjugates.
³H-α-ecdysone is irreversibly converted to ³H-β-ecdysone with an apparent $K_{m}$ which greatly exceeds endogenous substrate levels. Therefore saturation by substrate is unlikely to be a rate limiting factor in the synthesis of endogenous β-ecdysone. The conversion is product inhibited with an apparent $K_{I}$ of the same order of magnitude as the maximal concentration of endogenous product. Therefore, product inhibition may be a rate limiting factor in vivo.
Hormonal inactivating systems have apparent $K_{m}$ 's which greatly exceed physiological hormone levels, and, in mature larvae, are stimulated by high doses of exogenous β-ecdysone. These features make for a large and elastic capacity for hormonal inactivation in mature larvae.
Rates of ³H-molting hormone metabolism decrease when mature larvae form puparia. The activity of the system for converting ³H-α-ecdysone to ³H-β-ecdysone decreases by nearly three-fourths, and the half-life of ³H-β-ecdysone increases from 1.5 to 20 hr. Since endogenous β-ecdysone titer increases at this time, these data suggest that conversion of α- to β-ecdysone does not have, but inactivation may have, an important rôle in regulating β-ecdysone titer.
The apparent requirement of two hormones, α- and β-ecdysone, for molting induction in insects
1973, Developmental Biology
Puff formations at loci I-18-C and IV-2-B of the salivary gland chromosomes are early indications of a beginning molting process in Chironomus tentans larvae. The effectiveness of the two ecdysone analogs, α- and β-ecdysone, in inducing these puffs was compared. Incubation of salivary glands in vitro with β-ecdysone causes only puff IV-2-B to appear; incubation with α-ecdysone stimulates initially puffing at only I-18-C. After an injection of α-ecdysone, puffing at I-18-C begins within less than 15 min, whereas puffing at IV-2-B is delayed for more than 30 min. Following an injection of β-ecdysone, puffing at IV-2-B begins within less than 15 min, whereas puffing at I-18-C is delayed. Injected ³H-α-ecdysone is converted to β-ecdysone and a polar compound. Injected ³H-β-ecdysone is converted to a compound less polar than α-ecdysone and a polar metabolite which stimulates puffing at I-18-C, like α-ecdysone. It is suggested that the two ecdysones have different targets in the cell, that they can be rapidly converted to compounds with the activity of the other analog, and that the induction of a complete molt requires the action of both hormones.
Steroids and Biologically Related Compounds
1970, Annual Reports in Medicinal Chemistry
This chapter reviews the chemistry and biology of steroidal antibiotics and the microbiological degradation of steroids. Among estrogen–progestin combinations, a combination of quinestrol (17α-ethynyl estradiol 3-cyclopentyl ether) and quingestanol was clinically effective given orally, once a month. Quinestrol is stored in the body fat and released slowly throughout the cycle causing infertility. A once-a-month oral contraceptive may be well suited for underdeveloped countries where medical supervision is limited. Norgestrel (17a-ethynyl-18-methyl-19-nortestosterone), in combination with thynyl estradiol showed good contraceptive efficacy given 21 days in a cycle. Diabetic patients with endometrial carcinoma receiving medroxyprogesterone acetate required higher doses of insulin. The diabetogenic effect of contraceptives was not demonstrated in an insulin B-chain induced hyperglycemic rat. Increased iron and iron binding capacity was found with combined contraceptive therapy especially if the progestin was a 17α-acetoxy-20-ketosteroid. On one hand, oral contraceptives increased serum levels of copper and ceruloplasmin. On the other hand, evidence was presented showing that long-term use of norethynodrel and mestranol caused no frank toxicity, while in a short-term study, patients on placebo had similar side-effects to those found in women on contraceptive therapy.
