The invention provides compounds, compositions, and methods for studying the Rohmer pathway and for treating bacterial infections or parasitic infections. The parasitic infection can be a protozoan infection, such as malaria. The compounds and compositions can also be used as antibiotics, for example, to kill bacteria or parasites, or to inhibit bacterial or parasite growth. The invention further provides inhibitors of isoprenoid biosynthesis enzymes, and methods of inhibiting the activity of isoprenoid biosynthesis enzymes. The compounds can be, for example, alkynes or allenes that bind to a unique Fe of an Fe

Abstract We have isolated two dithiapolyacetylenes from the roots of Chaenactisdouglasii and from the plant roots as well as root cultures of Eriophyllum lanatum , namely 1-(2-methylethyn)-4-(hex-1,3-diyn-4-ene)-2,3-dithiacyclohexa-4,6-diene, and 1-(4-methylbut-1,3-diyn)-4-(but-1-yn-3-ene)-2,3-dithiacyclohexa-4,6-diene. We propose the trivial names thiarubrine A and thiarubrine B for these compounds

irradiation of thiarubrines resulted in the formation of novel 2,6‐dithiabicyclo[3.1.0]hex‐3‐ene polyyne photointerme‐diates (photosulfides) that rapidly undergo desulfuriza‐tion to yield thiophenes. Six photosulfides, photosulfides 3a and 3a' from thiarubrine A (la), photosulfides 3b and 3b' from thiarubrine B (lb) and photosulfides 3c and 3c' from thiarubrine D (lc) were characterized. Thiarubrine photointermediates
摘要。Thiarubrines 是一组由星状植物产生的深红色含硫色素,不耐光,暴露在紫外线或可见光下时会产生噻吩和元素硫。研究了从菊科植物(Ambrosia chamis-sonis)的根中分离出的硫红素 A (la)、B (lb) 和 D (lc) 的这种光诱导转化的机制。硫杂红素的可见光照射导致形成新型 2,6-二硫杂双环 [3.1.0] 己-3-烯聚炔光中间体(光硫化物),该中间体快速脱硫产生噻吩。表征了六种光硫化物,来自硫杂红素 A (1a) 的光硫化物 3a 和 3a'、来自硫杂红素 B (lb) 的光硫化物 3b 和 3b' 以及来自硫杂红素 D (lc) 的光硫化物 3c 和 3c'。硫红素光中间体寿命短且不稳定,硫红素 A 形成的光硫化物在室温下的半衰期为 12.3 分钟。虽然挤出的硫的直接命运尚不清楚,但我们使用电子轰击质谱法在硫代红素 A 的光解溶液中鉴定了环八硫 (S8)。用硫红素
