The compounds of the invention exhibit antiprotozoal, antimicrobial, and anticancer properties that are useful for the treatment or prevention of infections or cancer in a patient (e.g., a human). For example, the compounds and methods described herein can be used for the treatment or prevention of protozoal infections such as leishmaniasis, malaria, and
trypanosoma
infections, bacterial infections such as
S. aureus
and
C. albicans
, and cancers such as breast, colon, lung, or prostate cancer. The invention further provides methods of synthesizing such compounds as well as kits useful for administering the compounds.

Four convergent syntheticapproaches to acetoxyenediynes have been explored to gain access to peyssonenynes A and B, which are natural products isolated from the red alga Peyssonelia caulifera. After optimization of the routes with a palmitic acid based model system, the synthesis of the peyssonenynes was completed by using, as the key steps, 1) Ni/Cu co-catalyzed cross-coupling of terminal alkynes
derivatives, rac-35, rac-36, rac-37, rac-38, rac-39 and rac-40, and assessed their cytotoxic activity against NSCLC cells and diploid fibroblasts. SAR studies revealed that the alcohol moiety at position 3 and its absolute R configuration both were essential for the tumor cell line selective activity while for its cytotoxic magnitude the alkyl chain length and branching were of less significance.

A novel epigenetic modulator that displays a DNMT1 inhibition and DNMT3A activation profile was characterized (compound 8). This compound is a derivative of palmitic acid that incorporates the putative reactive functional group (diynone) of the peyssonenynenaturalproducts. Other analogues containing the diynone or an acetoxyenediyne did not show the same biological profile. In U937 human leukemia

Simply convergent: The polydeoxypropionates 1 and 2 are important constituents of the cell wall of Mycobacterium tuberculosis. Key steps in their total synthesis include two Suzuki–Miyaura cross‐coupling reactions and two highly diastereoselective iridium‐catalyzed hydrogenations. The trideoxypropionates employed as central building blocks were prepared by sequential oxy‐Cope rearrangement, hydrogenation
