Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Stereochemistry
  • Sponge

His main research concerns Stereochemistry, Sponge, Biochemistry, Alkaloid and Organic chemistry. His Stereochemistry research includes elements of Phenols and Tunicate. His study in the field of Tedania ignis and Aplysina fistularis is also linked to topics like Spectral data, Tedanolide and High resolution.

His study in the field of Enzyme and Okadaic acid also crosses realms of Bryostatins. His Okadaic acid study combines topics from a wide range of disciplines, such as Protein phosphatase 2 and Halichondria. His Carboxylic acid study, which is part of a larger body of work in Organic chemistry, is frequently linked to Natural compound, Animal origin and Episulfide, bridging the gap between disciplines.

His most cited work include:

  • Okadaic acid, a cytotoxic polyether from two marine sponges of the genus Halichondria (626 citations)
  • Structure-activity relationship within a series of okadaic acid derivatives. (122 citations)
  • Minor and trace sterols in marine invertebrates. 26. Isolation and structure elucidation of nine new 5.alpha.,8.alpha.-epidoxy sterols from four marine organisms (121 citations)

What are the main themes of his work throughout his whole career to date?

Francis J. Schmitz mainly focuses on Stereochemistry, Sponge, Organic chemistry, Animal origin and Biochemistry. When carried out as part of a general Stereochemistry research project, his work on Terpenoid, Diterpene and Sesquiterpene is frequently linked to work in Spectral data and Spectral analysis, therefore connecting diverse disciplines of study. His work in Diterpene addresses subjects such as Gorgonian, which are connected to disciplines such as Coelenterata.

His biological study spans a wide range of topics, including Derivative and Carbon-13 NMR. In general Organic chemistry, his work in Ether and Ene reaction is often linked to Aplysia dactylomela linking many areas of study. His Phosphatase, Enzyme, Okadaic acid and Protein kinase A study in the realm of Biochemistry connects with subjects such as Tyrosine kinase.

He most often published in these fields:

  • Stereochemistry (60.47%)
  • Sponge (33.14%)
  • Organic chemistry (22.09%)

What were the highlights of his more recent work (between 1996-2017)?

  • Stereochemistry (60.47%)
  • Sponge (33.14%)
  • Organic chemistry (22.09%)

In recent papers he was focusing on the following fields of study:

Francis J. Schmitz mostly deals with Stereochemistry, Sponge, Organic chemistry, Animal origin and Diterpene. By researching both Stereochemistry and Spectral data, Francis J. Schmitz produces research that crosses academic boundaries. His Sponge research incorporates elements of Sesquiterpene and Derivative.

The various areas that Francis J. Schmitz examines in his Diterpene study include Junceella juncea, Gorgonian, Indian ocean and Lactone. His research integrates issues of Metabolite and Mollusca, Pleurobranchus in his study of Terpenoid. His Tunicate research is multidisciplinary, relying on both Fascaplysin, Alkaloid, Didemnum, Prenylation and Aplidium.

Between 1996 and 2017, his most popular works were:

  • Comparison of fascaplysin and related alkaloids: a study of structures, cytotoxicities, and sources. (90 citations)
  • New cyclic peptides from the ascidian Lissoclinum patella. (71 citations)
  • Structures and cytotoxicities of fascaplysin and related alkaloids from two marine phyla—Fascaplysinopsis sponges and Didemnum tunicates (47 citations)

In his most recent research, the most cited papers focused on:

  • Organic chemistry
  • Sponge
  • Stereochemistry

His primary areas of investigation include Stereochemistry, Sponge, Animal origin, Organic chemistry and Terpenoid. His Stereochemistry study frequently draws connections to adjacent fields such as Tunicate. The concepts of his Sponge study are interwoven with issues in Derivative, Phosphatase, Biochemistry and Serine.

His work on Nuclear magnetic resonance spectroscopy, Adduct and Degree of unsaturation as part of general Organic chemistry study is frequently linked to Fragmentation and Tandem mass spectrometry, bridging the gap between disciplines. His Terpenoid research integrates issues from Sesquiterpene and Diterpene. His work on Fascaplysinopsis as part of general Alkaloid study is frequently linked to Pharmacognosy, therefore connecting diverse disciplines of science.
