Anastrozole (Arimidex), letrozole (Femara), and exemestane (Aromasin) are members of the third generation of aromatase inhibitors that has now replaced aminoglutethimide (Cytadren), the progestins, and tamoxifen (Nolvadex) as the hormonal therapy of choice in estrogen-receptor-positive, postmenopausal, metastatic breast cancer. This article will review the role of aromatase in the pathogenesis of breast cancer and the results of recent studies that have established the role of its inhibitors in estrogen-receptor-positive breast cancer. We will also briefly outline the rationale and design of ongoing studies. [ONCOLOGY 15(8):965-979, 2001]

When tested in vitro , 7-keto appears to activate the beta subset of the estrogen receptor (ERβ) with an EC 50 around 500μM which is partially blocked by exemestane (aromatase inhibitor or AI); there was no apparent activity on the classical subset (ERα) and parent DHEA and DHEAS were eqipotent. [45] As activity was hindered with an AI and there was efficacy in HepG2 cells but not Hep293 (expressing [46] and not expressing [47] aromatase, respectively) it is though that 7-oxo can be metabolized into an estrogen.

Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more [38] or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram. [39] [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography . [2] : 10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity. [39]

Hi, I have mild cardiovascular disease but am only in my mid-fifties. I am very slim, extremely fit, vegan, with a great HDL and triglycerides profile and fabulous HDL/LDL ratio (so clearly my problem is not dietary) but have high LDL cholesterols for familial/genetic reasons as well as high BP. Doctors have tried me with statins (just 8 weeks’ use caused muscle damage and inflammation as well as abnormal liver function tests) and I cannot take ezetimibe (ezetrol) to lower my LDLs as it causes tingling in my extremities and severe depression (suicidal ideation.) I have some pueraria mirifica, bought originally for breast enhancement and daren’t use it, in case it makes my atherosclerotic plaques worse, because my GP said I can’t take HRT owing to my existing cardiovascular plaques. I’ve heard that PM improves your lipids profile, though (and in my case could resolve some of the breast and skin looseness problems I’m having post-menopause) and wondered if it might be safe to take in patients with existing atherosclerosis whereas conventional HRT is not. Does anyone in a similar position or know anything about this?

In the past several years, some newer medications have come on the market; these are commonly referred to as COX-2 inhibitors . Remember, all NSAIDs work against cyclooxygenase (COX). Traditional NSAIDs (. Ibuprofen, Motrin, Aleve) work against both COX-1 and COX-2. COX-1 and COX-2 are both types of cyclooxygenase enzymes that function in your body. The new medications (. Celebrex) work primarily against COX-2, and allow COX-1 to function normally. Because COX-1 is more important in producing the protective lining in your gut (gastric mucosa), these newer NSAIDs are believed to have less of a risk of causing stomach ulcers.
