The antineoplastic properties of alpha-carboline, alpha-carboline hydrochloride, alpha-carboline N-1 methyl iodide and c-6 substituted fluoro-, chloro, nitro- and phenyl-alpha-carboline were studied. None of the compounds proved to be active when tested against i.p. transplanted B16 melanoma or i.m. implanted Lewis lung carcinoma. In addition, alpha-carboline was assessed against i.p. inoculated plasmacytoma MP26 and colon carcinoma 26, and solid tumors of mammary carcinoma 16/C and Walker carcinosarcoma 256. Under conditions tested these neoplasms did not respond to alpha-carboline.

Article Synopsis
- A new method was developed that allows for the reaction of 3-(2-isocyanoethyl)indoles with 1-sulfonyl-1,2,3-triazoles without the need for a catalyst.
- This process, called dearomative spirocyclization, efficiently creates polycyclic indolines that contain a spiro-α-carboline structure.
- The reaction takes place in a single step through thermal conditions, yielding the desired compounds in moderate to high amounts.

α-carboline (9-pyrido[2,3-]indole), contains a pyridine ring fused with an indole backbone, is a promising scaffold for medicinal chemistry. In recent decades, accumulating evidence shows that α-carboline natural products and their derivatives possess diverse bioactivities. However, hitherto, there is no comprehensive review to systematically summarize this important class of alkaloids.

The mitogen-activated protein kinase kinase 4 (MKK4) has recently been identified as druggable target for the treatment of acute liver failure in RNAi experiments. In these experiments MKK4 was identified to be a major regulator in hepatocyte regeneration. Inhibitors thereof may serve as medication to promote liver regeneration or reducing hepatocyte death.
