- 2000, Mohammed Y. Kalimi & ‎William Regelson, Dehydroepiandrosterone (DHEA), →ISBN:
  Work historically performed by toxicologists has provided an impressive list of endogenous and exobiotic compounds termed peroxisome proliferators (PP) which were so named for their ability following chronic high dose administration to rodents, to increase the number and activities of an essential intracellular organelle termed the peroxisome.
- 2012, Henrik S. Thomsen, ‎Robert N. Muller & ‎Robert F. Mattrey, Trends in Contrast Media, →ISBN, page 185:
  Little is known about the clinical safety of exobiotic polymers.
- 2013, B.B. Biswas & ‎H.K. Das, Plant-Microbe Interactions, →ISBN, page 74:
  Due to soil types and other exobiotic factors (e.g water supply and temperature) many microenvironments may be present, leading to the need for polysaccharides adapted to these conditions.
- 2015, Maxim Ryadnov & ‎Ferenc Hudecz, Amino acids, peptides and proteins: Volume 40, →ISBN, page 18:
  In any case, OXLs from C^α-trisubstituted residues were extensively employed for the preparation of enantiomerically α-amino acid derivatives and C^α-tetrasubstituted α-amino acids (in the latter experiments, also in the context of investigations in the prebiotic and exobiotic fields).
Of or pertaining to exobiology.
- 1981, Proceedings - Volume 23, page 109:
  For example, terran contamination could result in the introduction of exobiotic organisms, the initiation of chemical reactions or changes, or the mutation of either 12 indigenous or exogenous organisms.

  Around me were computer databases filled with records of innumerable galaxies, exobiotic life forms and extraterrestrial cultures.

Derived terms

exobiotically

Noun

exobiotic (plural exobiotics)

(medicine) An exobiotic substance, especially one that influences the functioning of an organ or biological process.
- 1996, Philip W. Harvey, Adrenal in Toxicology: Target Organ and Modulator of Toxicity, →ISBN, page 74:
  We have listed an example of an exobiotic which influences each identified step, but it should be remembered that this is far from an exhaustive list of the exobiotics which affect adrenal function.
- 2010, Pere Ginès, Chronic Liver Failure: Mechanisms and Management, page 43:
  The liver is exposed to millions of antigens and exobiotics. If every contact would stimulate the immune system, the liver would be in a permanent state of inflammation.
- 2006, Sarfaraz K. Niazi, Handbook of Preformulation: Chemical, Biological, and Botanical Drugs:
  ADME and chemical reactivity-related toxicity is low, while biological receptor activity is of higher dimension in chemistry space, and this is partly explainable by evolutionary pressures on ADME to deal with endobiotics and exobiotics.
