Insights

Artocarpus altilis leaf extract shows preferential cytotoxicity against pancreatic cancer cells under nutrient starvation. New compounds, sakenins F and H, exhibit potent antiausterity activity, offering novel anticancer drug discovery avenues.

Area of Science:

  • Natural product chemistry
  • Cancer biology
  • Pharmacology

Background:

  • Human pancreatic cancer cells exhibit remarkable tolerance to nutrient starvation, aiding survival in the tumor microenvironment.
  • Targeting cancer cell survival under low nutrient conditions represents a novel antiausterity strategy in anticancer drug discovery.

Purpose of the Study:

  • To identify agents that preferentially inhibit the survival of cancer cells under nutrient-deprived conditions.
  • To investigate the antiausterity potential of Artocarpus altilis leaf extract and its constituents.

Main Methods:

  • Methanolic extraction of Artocarpus altilis leaves.
  • Cytotoxicity assays on PANC-1 human pancreatic cancer cells under nutrient-deprived conditions.
  • Isolation and structural elucidation of compounds from the extract using chromatographic and spectroscopic techniques.

Main Results:

  • The Artocarpus altilis methanolic extract demonstrated 100% preferential cytotoxicity against PANC-1 cells at 50 µg/mL under nutrient starvation.
  • Eight new geranylated dihydrochalcones (sakenins A-H) and four known compounds were isolated.
  • Sakenins F (PC50 = 8.0 µM) and H (PC50 = 11.1 µM) were identified as potent preferentially cytotoxic agents.

Conclusions:

  • Artocarpus altilis is a potential source of novel antiausterity compounds for pancreatic cancer therapy.
  • Sakenins F and H represent promising lead compounds for developing new anticancer drugs targeting nutrient-deprived cancer cells.

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors

α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.
Acarbose and miglitol are...

Cholinergic Antagonists: Chemistry and Structure-Activity Relationship

Cholinergic antagonists bind to cholinergic receptors and limit the effects of acetylcholine and other cholinergic agonists. Based on the specific cholinergic receptor affinity, these antagonists are classified as muscarinic or nicotinic. Anticholinergics interrupt parasympathetic innervations while sympathetic innervations remain uninterrupted. Muscarinic antagonists are also called 'muscarinic antagonists', 'antimuscarinics', or 'parasympatholytics'. Nicotinic...

Cholinergic Antagonists: Therapeutic Uses

Antimuscarinic drugs have various therapeutic applications by inhibiting parasympathetic stimulation in different systems. Here are the key therapeutic uses of antimuscarinics:    
Respiratory Tract: Ipratropium, aclidinium, and tiotropium treat asthma, chronic bronchitis, and chronic obstructive pulmonary disease (COPD). They protect against bronchoconstriction caused by irritants like cigarette smoke, sulfur dioxide, and ozone. They also help reduce nasopharyngeal...

Indirect-Acting Cholinergic Agonists: Pharmacological Actions

Indirect-acting cholinergic agonists, also known as anticholinesterases, exert their pharmacological effects by enhancing cholinergic transmission in various body parts, including the neuromuscular junction, autonomic cholinergic synapses, and the brain.
At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...

Cholinergic Antagonists: Pharmacological Actions

Antimuscarinic drugs block muscarinic receptors in multiple systems, including the gut, eye, smooth muscles, respiratory tract, cardiovascular, and central nervous systems. They produce similar effects with varying selectivity depending on the specific agent and tissue. Here are the key pharmacological actions of antimuscarinics:
Gastrointestinal Effects: Antimuscarinics reduce gut contractions, increase gastric emptying, and slow intestinal transit. They partly inhibit gastric acid secretion...

Cholinergic Antagonists: Pharmacokinetics

Cholinergic antagonists—such as antimuscarinics—are available in oral, topical, ocular, parenteral, and inhalational formulations. Most antimuscarinics are oral formulations,  while scopolamine is available as a topical patch, and ipratropium and tiotropium are available as inhalation aerosols or powders. Atropine, tropicamide, and cyclopentolate are topically instilled in the eye. Most antimuscarinics are lipid-soluble and readily absorbed from the gastrointestinal tract and...
