Information

Lanreotide is a synthetic polypeptide analogue of somatostatin that resembles the native hormone in its ability to suppress levels and activity of growth hormone, insulin, glucagon and many other gastrointestinal peptides. Because its half-life is longer than somatostatin, lanreotide can be used clinically to treat neuroendocrine tumors that secrete excessive amounts of growth hormone (acromegaly) or other active hormones or neuropeptides. Lanreotide has many side effects including suppression of gall bladder contractility and bile production, and maintenance therapy may cause cholelithiasis and pancreatitis as well accompanying liver injury.

Biologic Description

Toxicity PubChem|10796238

In preregistration studies of lanreotide, serum enzyme levels did not change appreciably and there were no reports of clinically apparent acute liver injury. Pooled analyses reported that there were no overall changes in serum ALT, AST or alkaline phosphatase levels during therapy or instances of clinically meaningful elevations with treatment. Prolonged therapy with lanreotide, as with other somatostatin analogues, was associated with a high rate of biliary sludge and cholelithiasis, probably due to inhibition of gall bladder contractility and decrease in bile secretion. In long term studies, cholelithiasis developed in 20% to 33% of lanreotide treated patients. In some instances, symptomatic cholecystitis occurred which can be accompanied by mild-to-moderate elevations in serum enzymes and bilirubin. However, most lanreotide associated gallstones were asymptomatic. Unlike octreotide, lanreotide and other long acting somatostatin analogues have not been liked to cases of clinically apparent liver injury, independent of cholelithiasis or biliary sludge, although they have had more limited use and have not been used in many of the clinical situations that were treated with octreotide (portal hypertension, variceal hemorrhage and infants with congenital hyperinsulinemia).

Coibamide A, a potent antiproliferative cyclic depsipeptide from the Panamanian marine cyanobacterium Leptolyngbya sp

Abstract

  • Coibamide A (1) is a new, potent antiproliferative depsipeptide which was isolated from a marine Leptolyngbya cyanobacterium collected from the Coiba National Park, Panama. The planar structure of 1 was elucidated by a combination of NMR spectroscopy and mass spectrometry. Exhaustive 1D and 2D NMR spectroscopy included natural abundance 15N and variable temperature experiments; mass spectrometry included TOF-ESI-MSn and FT-MSn experiments. Chemical degradation followed by chiral HPLC- and GC-MS analyses was used to assign the absolute configuration of 1. This highly methylated cyclized depsipeptide exhibited an unprecedented selectivity profile in the NCI 60 cancer cell line panel and appears to act via a novel mechanism.

Coibamide A induces mTOR-independent autophagy and cell death in human glioblastoma cells

Abstract

  • Coibamide A is an N-methyl-stabilized depsipeptide that was isolated from a marine cyanobacterium as part of an International Cooperative Biodiversity Groups (ICBG) program based in Panama. Previous testing of coibamide A in the NCI in vitro 60 cancer cell line panel revealed a potent anti-proliferative response and "COMPARE-negative" profile indicative of a unique mechanism of action. We report that coibamide A is a more potent and efficacious cytotoxin than was previously appreciated, inducing concentration- and time-dependent cytotoxicity (EC50<100 nM) in human U87-MG and SF-295 glioblastoma cells and mouse embryonic fibroblasts (MEFs). This activity was lost upon linearization of the molecule, highlighting the importance of the cyclized structure for both anti-proliferative and cytotoxic responses. We show that coibamide A induces autophagosome accumulation in human glioblastoma cell types and MEFs via an mTOR-independent mechanism; no change was observed in the phosphorylation state of ULK1 (Ser-757), p70 S6K1 (Thr-389), S6 ribosomal protein (Ser-235/236) and 4EBP-1 (Thr-37/46). Coibamide A also induces morphologically and biochemically distinct forms of cell death according to cell type. SF-295 glioblastoma cells showed caspase-3 activation and evidence of apoptotic cell death in a pattern that was also seen in wild-type and autophagy-deficient (ATG5-null) MEFs. In contrast, cell death in U87-MG glioblastoma cells was characterized by extensive cytoplasmic vacuolization and lacked clear apoptotic features. Cell death was attenuated, but still triggered, in Apaf-1-null MEFs lacking a functional mitochondria-mediated apoptotic pathway. From the study of ATG5-null MEFs we conclude that a conventional autophagy response is not required for coibamide A-induced cell death, but likely occurs in dying cells in response to treatment. Coibamide A represents a natural product scaffold with potential for the study of mTOR-independent signaling and cell death mechanisms in apoptotic-resistant cancer cells.

Synthesis and biological evaluation of the [d-MeAla(11)]-epimer of coibamide A

Abstract

  • Coibamide A is a highly potent antiproliferative cyclic depsipeptide, which was originally isolated from a Panamanian marine cyanobacterium. In this study, the synthesis of coibamide A has been investigated using Fmoc-based solid-phase peptide synthesis followed by the cleavage of the resulting linear peptide from the resin and its subsequent macrolactonization. The peptide sequence of the linear coibamide A precursor was constructed on a solid-support following the optimization of the coupling conditions, where numerous coupling agents were evaluated. The macrocyclization of the resulting linear peptide provided the [d-MeAla(11)]-epimer of coibamide A, which exhibited nanomolar cytotoxic activity towards a number of human cancer cell lines.
