Abstract

Insights

Liver X receptor (LXR) agonists show promise for atherosclerosis treatment by upregulating cholesterol transport genes. Future LXR agonists must avoid lipogenic effects, with selective LXRalpha activation being a key strategy.

Area of Science:

  • Molecular biology and pharmacology
  • Cardiovascular research
  • Drug discovery

Background:

  • Liver X receptors (LXRs) regulate cholesterol metabolism, glucose homeostasis, and inflammation.
  • LXRs play a crucial role in reverse cholesterol transport (RCT), making them a target for atherosclerosis treatment.
  • Previous LXR agonists demonstrated target engagement but raised safety concerns regarding lipogenesis.

Purpose of the Study:

  • To review patents and biological data of LXR agonists from 2006-2009.
  • To analyze structure-activity relationships and identify key players in LXR agonist development.
  • To explore therapeutic indications for LXR agonists, particularly in atherosclerosis.

Main Methods:

  • Comprehensive patent analysis of LXR agonists (late 2006-August 2009).
  • Review of chemical properties and biological data of selected LXR analogues.
  • Examination of therapeutic applications and structure-activity relationships.

Main Results:

  • Overview of major LXR scaffolds and their structure-activity relationships.
  • Identification of key companies involved in LXR agonist research.
  • Demonstration of LXR target gene upregulation (ABCA1, ABCG1) by an LXR agonist in vitro.

Conclusions:

  • The clinical success of LXR agonists hinges on developing agents that lack lipogenic side effects.
  • Selective activation of LXRalpha is a promising strategy to achieve therapeutic benefits while minimizing adverse effects.
  • Further research is needed to identify safe and effective LXR agonists for treating metabolic and cardiovascular diseases.

Transducer Mechanism: Nuclear Receptors01:31

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test01:22

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...
Hepatic Drug Clearance: Role of Transporters01:14

Hepatic Drug Clearance: Role of Transporters

In the liver and bile canaliculi, influx and efflux transporters modification can influence intrinsic clearance. Transporters play a significant role in moving drugs within liver cells. Elaborate models, such as the Biopharmaceutical Classification System (BCS), are essential to relate transporters to drug disposition. This system categorizes drugs into four classes based on solubility and permeability, providing insights into elimination routes and the effects of transporters following oral...
Hepatic Drug Excretion: Influencing Factors01:16

Hepatic Drug Excretion: Influencing Factors

The biliary system of the liver, crucial for bile secretion and drug excretion, comprises intrahepatic bile ducts that merge to form the common hepatic duct. This duct, carrying hepatic bile, combines with the cystic duct, draining the gallbladder and forming the common bile duct, which empties into the duodenum. Bile, produced by hepatic cells lining the bile canaliculi, is composed primarily of water, bile salts, pigments, electrolytes, and lesser amounts of cholesterol and fatty acids. Bile...

Effect of Hepatic Disease on Pharmacokinetics: Active Drug, Metabolite and Fraction of Metabolized Drug

In pharmacotherapy, monitoring drug concentrations is paramount, especially for drugs whose therapeutic effects hinge on both the active compound and its metabolite. Hepatic impairment profoundly influences drug potency by altering liver function. If the drug is more potent than its metabolite, impaired liver function amplifies drug activity due to elevated drug concentration levels. Conversely, if the metabolite holds greater potency, diminished liver function diminishes drug activity by...
