Abstract:
A new ring A-seco triterpenoid, sentulic acid, along with a known oleanane-type triterpenoid, 3-oxoolean-12-en-27-oic acid, were isolated from the Indonesian plant Sandoricum koetjape Merr. Their chemical structures were elucidated by spectroscopic analysis. In addition, the cytotoxic effects of these compounds on human promyelocytic leukemia HL-60 cells were studied. The results of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays and trypan blue dye exclusion tests showed that sentulic acid and 3-oxoolean-12-en-27-oic acid were able to induce cytotoxicity in these cells. Furthermore, morphological examination and DNA fragmentation analysis indicated that these cytotoxic effects were mediated by apoptosis.

Nomenclature of Carboxylic Acid Derivatives: Acid Halides, Esters, and Acid Anhydrides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.

Preparation of Acid Anhydrides
The carboxylate ion acts as a nucleophile that attacks the carbonyl carbon of the acid chloride to form a tetrahedral intermediate. Subsequently, the re-formation of the carbonyl group with the loss of the chloride ion as a leaving group leads to the formation of an acid...
Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
