topics (OpenAlex): Porphyrin and Phthalocyanine Chemistry; Photodynamic Therapy Research Studies; Nanoplatforms for cancer theranostics
TL;DR: Three molecular designs have been developed wherein stable synthetic chlorins - analogues of chlorophylls - have been tailored with PEG groups for use in aqueous solution, augur well for development of a set of spectrally distinct chlorins with relatively sharp bands in the red region.

topics (OpenAlex): Porphyrin and Phthalocyanine Chemistry; Fluorine in Organic Chemistry; Synthesis and Characterization of Pyrroles
TL;DR: The synthesis of 53 compounds is described, encompassing 28 new compounds as well as 25 known compounds that have been more fully characterized or prepared via alternative routes that may prove useful in mainstream syntheses of diverse tetrapyrroles regardless of possible prebiotic relevance.

The Porphobilinogen Conundrum in Prebiotic Routes to Tetrapyrrole Macrocycles

Taniguchi, M., Ptaszek, M., Chandrashaker, V., & Lindsey, J. S. (2016, May 20). Origins of Life and Evolution of Biospheres, Vol. 47, pp. 93–119.

By: M. Taniguchi n , M. Ptaszek *, V. Chandrashaker n & J. Lindsey n 

Contributors: M. Taniguchi n , M. Ptaszek *, V. Chandrashaker n & J. Lindsey n 

author keywords: delta-aminolevulinic acid; Porphyrinogen; Porphyrin; DFT; Biosynthesis; Biomimetic
MeSH headings : Aminolevulinic Acid / analogs & derivatives; Aminolevulinic Acid / chemistry; Evolution, Chemical; Kinetics; Origin of Life; Porphobilinogen / chemistry; Tetrapyrroles / chemistry
topics (OpenAlex): Porphyrin Metabolism and Disorders; Porphyrin and Phthalocyanine Chemistry; Neonatal Health and Biochemistry
TL;DR: The results suggest efforts toward a biomimetic, enzyme-free route to tetrapyrroles from ALA should turn away from structure-directed reactions and focus on catalysts that orient the two aminoketones to form PBG in a kinetically controlled process, thereby avoiding formation of pseudo-PBG.

TL;DR: Twenty new chlorins (17 targets, 6 intermediates) have been prepared and the challenge associated with molecular designs that encompass the combination of "hydrophilic, bioconjugatable and wavelength-tunable" chiefly resides in the nature of the hydrophilic unit. (via Semantic Scholar)
