Increased Production of Taxoids in Suspension Cultures of Taxus globosa after Elicitation

, 2022
The objectives of this study were to investigate whether elicitors induce the production of taxoids in Taxus globosa by testing the hypothesis that the cells induce a greater accumulation of taxoids depending on the type and concentration of the elicitor

Taxoid profile in endophytic fungi isolated from Corylus avellana, introduces potential source for the production of Taxol in semi-synthetic approaches

Scientific Reports, 2022
Taxol (Paclitaxel) and its derivative taxanes are widely used in chemotherapy and treatment of different types of cancer. Although the extracted taxanes from Taxus sp. are currently used in semi-synthetic production of Taxol, providing alternative always

Anticancer regimens containing third generation taxanes SB-T-121605 and SB-T-121606 are highly effective in resistant ovarian carcinoma model

Frontiers in Pharmacology, 2022
Taxanes are widely used in the treatment of ovarian carcinomas. One of the main problems with conventional taxanes is the risk of development of multidrug resistance.

Taxane Diterpene Synthesis Studies. Part 1: Chemoenzymatic and Enantiodivergent Routes to AB-ring Substructures of Taxoids and ent -Taxoids

, 2015
The microbially derived cis-1,2-dihydrocatechol 2 has been converted, via reaction sequences including Diels-Alder cycloaddition and anionic oxy-Cope rearrangement steps, into enantiopure bicyclo[5.3.1]undecenes 21 and 34, which correspond to AB-ring ...

Isolation of taxoids from cell suspension cultures of Taxus wallichiana

, 2000
Cell suspension cultures of stem-derived callus of Taxus wallichiana in MS-F culture media were found to produce three C-14 oxygenated taxoids and one regular taxoid.

Engineering of 10‐Deacetylbaccatin III‐10‐β‐O‐Acetyltransferase From Taxus Species for Efficient Acetylating Non‐Natural Substrates Into Taxol in Nicotiana benthamiana

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3308-3323, May 2026.
ABSTRACT 7‐β‐xylosyl‐10‐deacetyltaxol (XDT) is much more abundant than the anticancer drug Taxol in Taxus species and is usually regarded as the by‐product of Taxol. It could be enzymatically transformed into 10‐deacetyltaxol (DT), and the latter could be further converted into Taxol.

Syntheses and Structure−Activity Relationships of the Second-Generation Antitumor Taxoids:  Exceptional Activity against Drug-Resistant Cancer Cells

, 2016
A series of new 3‘-(2-methyl-1-propenyl) and 3‘-(2-methylpropyl) taxoids with modifications at C-10 was synthesized by means of the β-lactam synthon method using 10-modified 7-(triethylsilyl)-10-deacetylbaccatin III derivatives.
