AI Article Synopsis

  • A method was developed to separate various alkaloids from gum opium using gradient high-performance liquid chromatography on a reversed-phase phenyl column.
  • The separation was achieved using a simple mobile phase of methanol and triethylammonium phosphate buffer, starting at 5% methanol and ending at 70% in 20 minutes.
  • This technique allows for precise analysis of the main alkaloids and requires minimal sample preparation, making it practical for routine use.

Article Abstract

The separation of the five principal alkaloids (morphine, codeine, thebaine, noscapine and papaverine), three minor alkaloids (laudanosine, cryptopine and narceine), meconic acid and some unidentified constituents in gum opium samples has been achieved on a reversed-phase phenyl column by gradient high-performance liquid chromatography using a simple and inexpensive mobile phase system. The linear gradient programme was started at 5% and ended at 70% methanol in triethylammonium phosphate buffer in 20 min. The five principal alkaloids were also determined with good precision. The method requires minimum sample preparation and is suitable for routine analysis.

Targeting DNA damage response (DDR) pathways represents one of the principal approaches in cancer therapy. However, defects in DDR mechanisms, exhibited by various tumors, can also promote tumor progression and resistance to therapy, negatively impacting patient survival. Therefore, identifying new molecules from natural extracts could provide a powerful source of novel compounds for cancer treatment strategies.

Article Synopsis
  • The study explored how psilocybin-assisted therapy (PAT) impacts personality traits in people with alcohol use disorder (AUD), hypothesizing it would reduce trait impulsiveness and improve drinking behavior.
  • Eighty-four AUD patients were divided into two groups (psilocybin vs. placebo) and assessed for changes in personality traits over time, finding significant personality shifts in the psilocybin group, including reduced neuroticism and increased openness.
  • The results indicated that lower impulsiveness correlated with decreased alcohol consumption, particularly among those who drank at risk before treatment, pointing to potential benefits of PAT in addressing both personality and drinking behaviors.
